drm/i915/display: Only write to register in intel_psr2_program_trans_man_trk_ctl()
There is no support for two pipes one transcoder for PSR and if we had
that the current code should not use cpu_transcoder.
Also I can't see a scenario where crtc_state->enable_psr2_sel_fetch is
set and PSR is not enabled and if by a bug it happens PSR HW will just
ignore any value in set in PSR2_MAN_TRK_CTL.
So dropping all the rest and keeping the same behavior that we have
with intel_psr2_program_plane_sel_fetch().
