d09ec6f987 clk: qcom: Use qcom_branch_set_clk_en() 
Instead of magically poking at the bit0 of branch clocks' CBCR, use
the newly introduced helper.

4f66879c76 clk: qcom: gcc-sm8250: Set delay for Venus CLK resets 
Some Venus resets may require more time when toggling. Describe that.

The value was obtained by referencing the msm-4.19 driver, which uses a
single value for all platforms [1].

GPLL9 is not on by default, which causes a "gcc_sdcc2_apps_clk_src: rcg
didn't update its configuration" error when booting. Set .flags =
CLK_OPS_PARENT_ENABLE to fix the error.

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.

ac1c5a03d3 clk: qcom: gcc-sm8250: Use retention mode for USB GDSCs 
USB controllers on SM8250 doesn't work after coming back from suspend.
This can be fixed by keeping the USB GDSCs in retention mode so that
hardware can keep them ON and put into rentention mode once the parent
domain goes to a low power state.
