clk: qcom: mmcc-sdm660: fix stuck video_subcore0 clock

[ Upstream commit 000cbe3896c56bf5c625e286ff096533a6b27657 ]

This clock can't be enable with VENUS_CORE0 GDSC turned off. But that
GDSC is under HW control so it can be turned off at any moment.
Instead of checking the dependent clock we can just vote for it to
enable later when GDSC gets turned on.
