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

Configure gcc_video_axi0_clk and gcc_video_axi1_clk clocks
to be enabled at all times. These clocks must be enabled
in order for QDSS packets to be timestamped properly.
These clocks will be physically disabled whenever MMNOC is turned off.
