ASoC: SOF: Add 'non_recoverable' parameter to snd_sof_dsp_panic()
Some platforms use retries during firmware boot to overcome DSP startup
issues.
In these cases we might receive a DSP panic message which should not be
treated as fatal if it happens during boot.

Pass this information to snd_sof_dsp_panic() and omit the panic print if
it is not fatal or the user does not want to see all dumps.

ASoC: SOF: OF: Avoid reverse module dependency
Similar with commit 8a49cd11e6 ("ASoC: SOF: ACPI: avoid reverse
module dependency") we will be having hardware specific drivers that
link against a common "helper" framework.

sof-of-dev.c becomes a library with the interface defined in the newly
created file sof-of-dev.h.

This is the final step started with Kconfig simplification in
commit 7548a391c5 ("ASoC: SOF: i.MX: simplify Kconfig")

ASoC: SOF: imx8: Add runtime PM / System PM support
Handle clocks and mailbox channels at runtime suspend/resume
in order to save power.

DSP runtime PM uses a timeout of 2s. If device
is idle for 2s system will enter runtime suspend.

Because SOF state machine assumes that even if the DSP wasn't previously
active at a System resume, will re-load the firmware we need to make sure
that all needed resources are active.

Kernel core will take care of enabling the PD, we need to make sure that
we request the MU channels.

ASoC: SOF: imx: Add code to manage DSP related clocks
We need at least 3 clocks in order to power up and access
DSP core registers found on i.MX8QM, i.MX8QXP and i.MX8MP
platforms.

Add code to request these clocks and enable them at probe. Next
patches will add PM support which will only activate clocks when
DSP is used.

DSP clocks are already documented in
Documentation/devicetree/bindings/dsp/fsl,dsp.yaml

We choose to add:
	* imx8_parse_clocks
	* imx8_enable_clocks
	* imx8_disable_clocks

wrappers because in the future DSP will need to take care about the
clocks of other related Audio IPs (e.g SAI, ESAI).

ASoC: SOF: imx: Add debug support for imx platforms
This patch adds debug support for imx platforms. This is important in
order to gather information about the state of the DSP in case of an

This is done by checking if a message with a panic code has been placed
in the debug box, in the imx8_dsp_handle_request function from sof/imx.

If positive, the function imx8_dump, added in common, will be called.
The first step is to gather information about the registers, filename,
line number and stack by calling the imx8_get_registers, added in common.
Then the information will be printed to the console by calling the
get_status function.

ASoC: SOF: imx8: Add ops for i.MX8QM
i.MX8QM and i.MX8QXP are mostly identical platforms with minor hardware
differences. One of these differences affects the firmware boot process,
requiring the run operation to differ. All other ops are reused.

ASoC: SOF: Rename i.MX8 platform to i.MX8X
i.MX8 and i.MX8X platforms are very similar and were treated the same.
Anyhow, we need to account for the differences somehow.

Current supported platform is i.MX8QXP which is from i.MX8X family.
Rename i.MX8 platform to i.MX8X to prepare for future i.MX8 platforms.

The semantic patch that makes this change is as follows:

ASoC: SOF: imx8: Fix dsp_box offset
dsp_box is used to keep DSP initiated messages. The value of dsp_offset
is set by the DSP with the first message, so we need a way to bootstrap
it in order to get the first message.

We do this by setting the correct default dsp_box offset which on i.MX8
is not zero.

Very interesting is why it has worked until now.

On i.MX8, DSP communicates with ARM core using a shared SDRAM memory
area. Actually, there are two shared areas:
	* SDRAM0 - starting at 0x92400000, size 0x800000
	* SDRAM1 - starting at 0x92C00000, size 0x800000

SDRAM0 keeps the data sections, starting with .rodata. By chance
fw_ready structure was placed at the beginning of .rodata.

dsp_box_base is defined as SDRAM0 + dsp_box_offset and it is placed
at the beginning of SDRAM1 (dsp_box_offset should be 0x800000). But
because it is zero initialized by default it points to SDRAM0 where
by chance the fw_ready was placed in the SOF firmware.

Anyhow, SOF commit 7466bee378dd811b ("clk: make freq arrays constant")
fw_ready is no longer at the beginning of SDRAM0 and everything shows
how lucky we were until now.

Fix this by properly setting the default dsp_box offset.

ASoC: SOF: define INFO_ flags in dsp_ops
Currently the INFO_ flags such as PAUSE/NO_PERIOD_WAKEUP are defined
in the SOF PCM core, which doesn't scale. To account for platform
variations, these flags need to be set in DSP ops.

This patch only moves the definitions and does not change any
functionality.
