The Venus driver requires vcodec GDSC to be ON in SW mode for clock operations and move it back to HW mode to gain power benefits. Earlier, as there is no interface to switch the GDSC mode from GenPD framework, the GDSC is moved to HW control mode as part of GDSC enable callback and venus driver is writing to its POWER_CONTROL register to keep the GDSC ON from SW whereever required. But the POWER_CONTROL register addresses are not constant and can vary across the variants. Also as per the HW recommendation, the GDSC mode switching needs to be controlled from respective GDSC register and this is a uniform approach across all the targets. Hence use dev_pm_genpd_set_hwmode() API which controls GDSC mode switching using its respective GDSC register.
