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.

f19dd2c243 clk: qcom: videocc-*: switch to module_platform_driver 
There is no need to register video clock controllers during subsys init
calls. Use module_platform_driver() instead.

4e32a9c2a3 clk: qcom: videocc-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-4.14/19 driver, which uses a
single value for all platforms [1].

b1ec8b53c9 clk: qcom: Drop mmcx gdsc supply for dispcc and videocc 
Both dispcc and videocc use mmcx power domain now.
Lets drop the supply mmcx from every gdsc.

a91c483b42 clk: qcom: videocc-sm8250: use runtime PM for the clock controller 
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.
