Two helpers have been added to the core to do all kind of controller
side configuration/initialization between the detection phase and the
final NAND scan. Implement these hooks so that we can convert the driver
to just use nand_scan() instead of the nand_scan_ident() +
nand_scan_tail() pair.

In the raw NAND core, a NAND chip is described by a nand_chip structure,
while a NAND controller is described with a nand_hw_control structure
which is not very meaningful.
Rename this structure nand_controller.
As the structure gets renamed, it is logical to also rename the core
function initializing it from nand_hw_control_init() to
nand_controller_init().
Lastly, the 'hwcontrol' entry of the nand_chip structure is not
meaningful neither while it has the role of fallback when no controller
structure is provided by the driver (the controller driver is dumb and
can only control a single chip). Thus, it is renamed dummy_controller.

The comment in marvell_nfc_select_chip() about ndtr0 and ndtr1 didn't
reflect what the driver was doing.
The values of NDTR0 and NDTR1 are read from the registers at probe time
and a copy is retained in 'struct marvell_nand_chip'. If keep-config is
set in the DT properties, there are no other writers of these timing
variables so they can safely be used when the chip is selected.
As suggested by Miquel Raynal, simply remove the comment.

This patch restores the suspend and resume hooks that the old driver used
to have. Apart from stopping and starting the clocks, the resume callback
also nullifies the selected_chip pointer, so the next command that is issued
will re-select the chip and thereby restore the timing registers.
Factor out some code from marvell_nfc_init() into a new function
marvell_nfc_reset() and also call it at resume time to reset some registers
that don't retain their contents during low-power mode.
Without this patch, a PXA3xx based system would cough up an error similar to
the one below after resume.

The code is doing monolithic reads for all chunks except the last one
which is wrong since a monolithic read will issue the
READ0+ADDRS+READ_START sequence. It not only takes longer because it
forces the NAND chip to reload the page content into its internal
cache, but by doing that we also reset the column pointer to 0, which
means we'll always read the first chunk instead of moving to the next
one.
Rework the code to do a monolithic read only for the first chunk,
then switch to naked reads for all intermediate chunks and finally
issue a last naked read for the last chunk.

One layout supported by the Marvell NAND controller supports NAND pages
of 2048 bytes, all handled in one single chunk when using BCH with a
strength of 4-bit per 512 bytes. In this case, instead of the generic
XTYPE_WRITE_DISPATCH/XTYPE_LAST_NAKED_RW couple, the controller expects
to receive XTYPE_MONOLITHIC_RW.
This fixes problems at boot like:

The block responsible of parsing the DT for the number of chip-select
lines uses an 'if/else if/else if' block. The content of the second and
third 'else if' conditions are:
1/ the actual condition to enter the sub-block and
2/ the operation to do in this sub-block.
[...]
else if (condition1_to_enter && action1() == failed)
raise_error();
else if (condition2_to_enter && action2() == failed)
raise_error();
[...]
In case of failure, the sub-block is entered and an error raised.
Otherwise, in case of success, the code would continue erroneously in
the next 'else if' statement because it did not failed (and did not
enter the first 'else if' sub-block).
The first 'else if' refers to legacy bindings while the second 'else if'
refers to new bindings. The second 'else if', which is entered
erroneously, checks for the 'reg' property, which, for old bindings,
does not mean anything because it would not be the number of CS
available, but the regular register map of almost any DT node. This
being said, the content of the 'reg' property being the register map
offset and length, it has '2' values, so the number of CS in this
situation is assumed to be '2'.
When running nand_scan_ident() with 2 CS, the core will check for an
array of chips. It will first issue a RESET and then a READ_ID. Of
course this will trigger two timeouts because there is no chip in front
of the second CS:
[ 1.367460] marvell-nfc f2720000.nand: Timeout on CMDD (NDSR: 0x00000080)
[ 1.474292] marvell-nfc f2720000.nand: Timeout on CMDD (NDSR: 0x00000280)
Indeed, this is harmless and the core will then assume there is only one
valid CS.
Fix the logic in the whole block by entering each sub-block just on the
'is legacy' condition, doing the action inside the sub-block. This way,
when the action succeeds, the whole block is left.
Furthermore, for both the old bindings and the new bindings the same
logic was applied to retrieve the number of CS lines:
using of_get_property() to get a size in bytes, converted in the actual
number of lines by dividing it per sizeof(u32) (4 bytes).
This is fine for the 'reg' property which is a list of the CS IDs but
not for the 'num-cs' property which is directly the value of the number
of CS.
Anyway, no existing DT uses another value than 'num-cs = <1>' and no
other value has ever been supported by the old driver (pxa3xx_nand.c).
Remove this condition and apply a number of 1 CS anyway, as already
described in the bindings.
Finally, the 'reg' property of a 'nand' node (with the new bindings)
gives the IDs of each CS line in use. marvell_nand.c driver first look
at the number of CS lines that are present in this property.
Better use of_property_count_elems_of_size() than dividing by 4 the size
of the number of bytes returned by of_get_property().
