Drivers should include only headers they use so drop:
1. of.h and of_address.h: When no OF call is used (of_device_id is
coming from mod_devicetable.h).
2. clk.h, property.h and reset-controller.h: No calls to clock consumer
or reset framework, no fwnode/property calls.

The previous wrapper qcom_cc_really_probe takes the platform
device as parameter, which is limited to platform driver.
As for qca8k clock controller driver, which is registered as
the MDIO device, which also follows the qcom clock framework.
To commonize qcom_cc_really_probe, updating it to take the
struct device as parameter, so that the qcom_cc_really_probe
can be utilized by the previous platform device and the new
added MDIO device.
Also update the current clock controller drivers to take
&pdev->dev as parameter when calling qcom_cc_really_probe.

pll_vco structure are never modified. They are used as .vco_table in
"struct clk_alpha_pll".
And in this structure, we have:
const struct pll_vco *vco_table;
Constifying these structures moves some data to a read-only section, so
increase overall security.

GPUCC has its own GPLL0 legs - one for 1-1 and one for div-2 output.
Add .name lookup to make sure older DTs consume the correct clock.

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.

A previous patch removes the "xo" clock from the global namespace making
it impossible to acquire by that ".name". The device-tree for msm8998
already provides the "xo" and "gpll0" clock since the addition of the
gpucc node making it unnecessary to have this fallback at all.

The GPU PLL0 is not a fixed PLL and the rate can be set on it:
this is necessary especially on boards which bootloader is setting
a very low rate on this PLL before booting Linux, which would be
unsuitable for postdividing to reach the maximum allowed Adreno GPU
frequency of 710MHz (or, actually, even 670MHz..) on this SoC.
To allow setting rates on the GPU PLL0, also define VCO boundaries
and set the CLK_SET_RATE_PARENT flag to the GPU PLL0 postdivider.
With this change, the Adreno GPU is now able to scale through all
the available frequencies.

The GPU GX GDSC has GPU_GX_BCR reset and gfx3d_clk CXC, as stated
on downstream kernels (and as verified upstream, because otherwise
random lockups happen).
Also, add PWRSTS_RET and NO_RET_PERIPH: also as found downstream,
and also as verified here, to avoid GPU related lockups it is
necessary to force retain mem, but *not* peripheral when enabling
this GDSC (and, of course, the inverse on disablement).
With this change, the GPU finally works flawlessly on my four
different MSM8998 devices from two different manufacturers.

Mark the msm8998 cpu CX gdsc as votable and use the hw control to avoid
corner cases with SMMU per hardware documentation.
