This should bring the fi-icl-dsi host on CI back online. It's using the
wrong registers for DSC.

Unfortunately intel_dsc_power_domain() remains broken for DSI, for all
generations. The rabbit hole goes deeper; POWER_DOMAIN_TRANSCODER() is
also broken for DSI transcoders, beyond DSC and beyond the recent gens.

But let's start here.

BR,
Jani.

Confirmed by [1] for fi-icl-dsi.
