The PCIe GDSCs can be shared with other masters and should use the APCS
collapse-vote register when updating the power state.
This is specifically also needed to be able to disable power domains
that have been enabled by boot firmware using the vote register.
Following other recent Qualcomm platforms, describe this register and
the corresponding mask for the PCIe (and _phy) GDSCs.

The PCIe GDSCs on most Qualcomm platforms expect the OS to always
consider collapse requests as successful. This also concerns SM8550.
Add the VOTABLE flag to the GDSCs in question to comply with these
expectations.

All of the 8550's GCC GDSCs can and should use the retain registers so
as not to lose their state when entering lower power modes.

Stromer Plus PLL found on IPQ53xx doesn't support dynamic
frequency scaling. To achieve the same, we need to park the APPS
PLL source to GPLL0, re configure the PLL and then switch the
source to APSS_PLL_EARLY.
To support this, register a clock notifier to get the PRE_RATE
and POST_RATE notification. Change the APSS PLL source to GPLL0
when PRE_RATE notification is received, then configure the PLL
and then change back the source to APSS_PLL_EARLY.
Additionally, not all SKUs of IPQ53xx support scaling. Hence,
do the above to the SKUs that support scaling.

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 and pull in various other headers. In
preparation to fix this, adjust the includes for what is actually needed.
of_device.h isn't needed, but mod_devicetable.h and platform_device.h were
implicitly included by it.

As it turns out, it's yet another interconnect bus clock. Move it
there. See [1] for reference.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() is renamed to .remove().
qcom_msm8996_cbf_icc_remove() returned zero unconditionally. After
changing this function to return void instead, the driver can be
converted trivially to use .remove_new().

According to a commit in the 3.4 vendor kernel sources[0] the
ocmemcx_ahb_clk clock "is controlled by RPM and should not be touched by
APPS.".

And indeed, when using MDSS+GPU+OCMEM on MSM8226 and not using
clk_ignore_unused, when Linux tries to disable the clock the device
crashes and reboots.
And since there's also no evidence of this clock in msm8974 vendor
kernel sources, remove the clock for msm8226 and msm8974.

The SMMU GDSC doesn't have to be ALWAYS-ON and shouldn't feature the
HW_CTRL flag (it's separate from hw_ctrl_addr). In addition to that,
it should feature a cxc entry for bimc_smmu_axi_clk and be marked as
votable.
Fix all of these issues.

Some branch clocks are governed externally and we're only supposed to
send a request concerning their shutdown, not actually ensure it happens.

If the parent clock rate is greater than unsigned long max/2 then
integer overflow happens when calculating the clock rate on 32-bit systems.
As RCG2 uses half integer dividers, the clock rate is first being
multiplied by 2 which will overflow the unsigned long max value.
Hence, replace the common pattern of doing 64-bit multiplication
and then a do_div() call with simpler mult_frac call.
