disp: msm: sde: avoid tx wait during DMS for targets with dsc rev2

Browse source 
This change removes tx_wait during DMS for targets which have
dsc_hw_rev_2. For targets with dsc_hw_rev_1, during DMS the
tx_wait is needed since DSC registers are not double buffered
and frame trigger needs to be serialized to avoid pp_timeout
issues.
