Do needed changes to handle PSR2_MAN_TRK_CTL correctly when DSB is in use: 1. Write PSR2_MAN_TRK_CTL in commit_pipe_pre_planes only when not using DSB. 2. Add PSR2_MAN_TRK_CTL writing into DSB commit in intel_atomic_dsb_finish. Taking PSR lock over DSB commit is not needed because PSR2_MAN_TRK_CTL is now written only by DSB.
