drm/i915/psr: Split sel fetch plane configuration into arm and noarm
SEL_FETCH_CTL registers are armed immediately when plane is disabled.
SEL_FETCH_* instances of plane configuration are used when doing
selective update and normal plane register instances for full updates.
Currently all SEL_FETCH_* registers are written as a part of noarm
plane configuration. If noarm and arm plane configuration are not
happening within same vblank we may end up having plane as a part of
selective update before it's PLANE_SURF register is written.
Fix this by splitting plane selective fetch configuration into arm and
noarm versions and call them accordingly. Write SEL_FETCH_CTL in arm
version.
v3:
- add arm suffix into intel_psr2_disable_plane_sel_fetch
v2:
- drop color_plane parameter from arm part
- dev_priv -> i915 in arm part
