clk: qcom: gcc-qdu1000: Update the RCGs ops

The clock RCGs are required to be parked at safe clock source(XO)
during disable as per the hardware expectation and clk_rcg2_shared_ops
are the closest implementation for the same. Hence update the clock
RCG ops to clk_rcg2_shared_ops.

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.
