[Intel-gfx] [PATCH] drm/i915: Use crtc_state->has_psr instead of CAN_PSR for pipe update

[Tarun Vyas]

In commit "drm/i915: Wait for PSR exit before checking for vblank
evasion", the idea was to limit the PSR IDLE checks when PSR is
actually supported. While CAN_PSR does do that check, it doesn't
applies on a per-crtc basis. crtc_state->has_psr is a more granular
check that avoids everything but pipe A, for the PSR IDLE check.

With this, the PSR IDLE check should be a *no-op* for all but pipe A
which is what was intended originally.

Fixes: a608987970b9 ("drm/i915: Wait for PSR exit before checking for
vblank evasion")
