Subject: [PATCH V5 4/5] clk: qcom: Use HW_CTRL_TRIGGER flag to switch video GDSC to HW mode

The HW_CTRL_TRIGGER flag provides flexibility to switch the GDSC
mode as per the consumers requirement compared to HW_CTRL flag which
directly switches the GDSC mode as part of gdsc enable/disable.
Hence use HW_CTRL_TRIGGER flag for vcodec GDSC's to allow venus driver
to switch the vcodec GDSC to HW/SW control modes at runtime using
dev_pm_genpd_set_hwmode() API.
