me about having dual licensing for DT stuff not dual license their

This is new. Why would we want the video clk parent state to turn off
when the CPU is off? Does the video engine keep XO enabled for itself?
Can you please add some comment into the code explaining why it's ok to
use the ao clk here?

This clock is from HW design is enabled, thus our generation scripts
have marked it to _ao. But I will be removing this in the next patch as
it is not required to be modelled.

Next patch will remove this clock. As it is already enabled from HW,
will not model the clock to not disable it from SW.
