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. In venus V6 variants, the vcodec gdsc gets enabled in SW mode by default with new HW_CTRL_TRIGGER flag and there is no need to switch it to SW mode again after enable, hence add check to avoid switching gdsc to SW mode again after gdsc enable. Similarly add check to avoid switching GDSC to HW mode before disabling the GDSC, so GDSC gets enabled in SW mode in the next enable.
