pm_runtime_put_autosuspend(), pm_runtime_put_sync_autosuspend(),
pm_runtime_autosuspend() and pm_request_autosuspend() now include a call
to pm_runtime_mark_last_busy(). Remove the now-reduntant explicit call to
pm_runtime_mark_last_busy().

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.
On a x86_64, with allmodconfig:

Instead of magically poking at the bit0 of branch clocks' CBCR, use

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.

The two devices managed by lpasscorecc-sc7180.c each had their own
"struct dev_pm_ops". This is not needed. They are exactly the same and
the structure is "static const" so it can't possible change. combine
the two. This matches what's done for sc7280.
This should be a noop other than saving a few bytes.

The sc7180 lpass clock controller's pm_runtime usage wasn't broken
quite as spectacularly as the sc7280's pm_runtime usage, but it was
still broken. Putting some printouts in at boot showed me this (with
serial console enabled, which makes the prints slow and thus changes
timing):
[ 3.109951] DOUG: my_pm_clk_resume, usage=1
[ 3.114767] DOUG: my_pm_clk_resume, usage=1
[ 3.664443] DOUG: my_pm_clk_suspend, usage=0
[ 3.897566] DOUG: my_pm_clk_suspend, usage=0
[ 3.910137] DOUG: my_pm_clk_resume, usage=1
[ 3.923217] DOUG: my_pm_clk_resume, usage=0
[ 4.440116] DOUG: my_pm_clk_suspend, usage=-1
[ 4.444982] DOUG: my_pm_clk_suspend, usage=0
[ 14.170501] DOUG: my_pm_clk_resume, usage=1
[ 14.176245] DOUG: my_pm_clk_resume, usage=0
...or this w/out serial console:
[ 0.556139] DOUG: my_pm_clk_resume, usage=1
[ 0.556279] DOUG: my_pm_clk_resume, usage=1
[ 1.058422] DOUG: my_pm_clk_suspend, usage=-1
[ 1.058464] DOUG: my_pm_clk_suspend, usage=0
[ 1.186250] DOUG: my_pm_clk_resume, usage=1
[ 1.186292] DOUG: my_pm_clk_resume, usage=0
[ 1.731536] DOUG: my_pm_clk_suspend, usage=-1
[ 1.731557] DOUG: my_pm_clk_suspend, usage=0
[ 10.288910] DOUG: my_pm_clk_resume, usage=1
[ 10.289496] DOUG: my_pm_clk_resume, usage=0
It seems to be doing roughly the right sequence of calls, but just
like with sc7280 this is more by luck than anything. Having a usage of
-1 is just not OK.
Let's fix this like we did with sc7280.

The sc7180 lpass clock driver manages two different devices. These
two devices were tangled together, using one probe and a lookup to
figure out the real probe. I think it's cleaner to really separate
the probe for these two devices since they're really different things,
just both managed by the same driver.
