Revert "clk: qcom: gcc-kona: configure video axi clocks to be always-on"

This reverts commit 3c0c5b54.
Keeping gcc_video_axi0_clk and gcc_video_axi1_clk clocks enabled
at all times causes problems for video core power collapse.
In particular, doing so leads to a NOC error each time that the
video core is power collapsed.
