On sm8250 dispcc and videocc registers are powered up by the MMCX power
domain. Use runtime PM calls to make sure that required power domain is
powered on while we access clock controller's registers.

On sm8250 videocc requires MMCX power domain to be powered up before
clock controller's registers become available. For now sm8250 was using
external regulator driven by the power domain to describe this
relationship. Switch into specifying power-domain and required opp-state
directly.

As shown downstream[1], this GDSC supports HW trigger mode and
we're supposed to enable it in order to ensure correct operation.

As also shown on downstream dts[1], for a correct operation of the
Venus block, we have to retain MEM/PERIPH when halting the video_core,
video_axi and video_subcore0 branches: add these CXCs to the main
Venus GDSC.

As there is a `rate` field in clk_smd_rpm, clk_smd_rpm_recalc_rate() can
be used by branch clocks to report rate as well, rather than assuming
the rate is always same as parent clock. This assumption doesn't hold
on platforms like QCM2290, where xo_board is 38.4MHz while bi_tcxo is
19.2MHz.
To get this work, XO buffered clocks need the following updates.
- Assign a correct rate rather than the fake one which is being used to
generate binary value for clk_smd_rpm_req interface.
- Explicitly handle the clk_smd_rpm_req interface value for XO buffered
clocks (.rpm_res_type being QCOM_SMD_RPM_CLK_BUF_A).

Add Global Clock Controller (GCC) driver for QCM2290. This is a porting
of gcc-scuba driver from CAF msm-4.19, with GDSC support added on top.
Because the alpha_pll on the platform has a different register
layout (offsets), its own clk_alpha_pll_regs_offset[] is used in the
driver.
