clk: qcom: camcc-sdm845: Specify Titan GDSC power domain as a parent to other

When a consumer turns on/off a power domain dependent on another power
domain in hardware, the parent power domain shall be turned on/off by
the power domain provider as well, and to get it the power domain hardware
hierarchy shall be properly described in the power domain provider driver.

Establish the power domain hierarchy with a Titan GDSC set as a parent of
other GDSC power domains provided by the SDM845 camera clock controller,
including IPE0/1 and BPS ones.
