7e1723fd3f clk: meson: migrate meson-aoclk out of hw_onecell_data to drop NR_CLKS
The way hw_onecell_data is declared:
  struct clk_hw_onecell_data {
          unsigned int num;
          struct clk_hw *hws[];
  };

makes it impossible to have the clk_hw table declared outside while
using ARRAY_SIZE() to determine ".num" due to ".hws" being a flexible
array member.

Completely move out of hw_onecell_data and add a custom
devm_of_clk_add_hw_provider() "get" callback to retrieve the clk_hw
from the meson_aoclk_data struct to finally get rid on the
NR_CLKS define.

a96cbb146a clk: Explicitly include correct DT includes
The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

072a043f5a clk: meson: remove ao input bypass clocks
During probe, bypass clocks (i.e. ao-in-xtal) are made from device-tree
inputs to provide input clocks which can be access through global name.
The cons of this method are the duplicated clocks, means more string
comparison.

Specify parent directly with device-tree clock name.

Function to regiter bypass clocks is removed.

Input parameters from meson aoclk data structure are deprecated and then
deleted since all aoclk files are migrated.

889c2b7ec4 clk: meson: rework and clean drivers dependencies
Initially, the meson clock directory only hosted 2 controllers drivers,
for meson8 and gxbb. At the time, both used the same set of clock drivers
so managing the dependencies was not a big concern.

Since this ancient time, entropy did its job, controllers with different
requirement and specific clock drivers have been added. Unfortunately, we
did not do a great job at managing the dependencies between the
controllers and the different clock drivers. Some drivers, such as
clk-phase or vid-pll-div, are compiled even if they are useless on the
target (meson8). As we are adding new controllers, we need to be able to
pick a driver w/o pulling the whole thing.

The patch aims to clean things up by:
* providing a dedicated CONFIG_ for each clock drivers
* allowing clock drivers to be compiled as a modules, if possible
* stating explicitly which drivers are required by each controller.

8d9981efbc clk: meson: clean-up clock registration
Order, ids and size  between the table of regmap clocks and the onecell
data table could be different.

Set regmap pointer in all the regmap clocks before starting the
registration using the onecell data, to make sure we don't
get into an incoherent situation.
