Subject: [PATCH v2 5/6] clk: qcom: videocc-sm8550: Use HW_CTRL_TRIGGER instead of HW_CTRL for GDSC

From: Jagadeesh Kona <quic_jkona@...cinc.com>

HW_CTRL moves the GDSC to HW control mode as part of GDSC enable itself.
Use HW_CTRL_TRIGGER flag instead of HW_CTRL flag for video GDSC's to
switch the GDSC to HW/SW control modes only when consumer requested to
switch GDSC mode using dev_pm_genpd_set_hwmode.
