[Intel-gfx] [PATCH 6/7] drm/i915: Remove psr re-activation delay on HSW+.

[Rodrigo Vivi]

commit 97173eaf5f3 ("drm/i915: PSR: Increase idle_frames")
incresed the number of idle frames making PSR entry more
reliable on many panels. Also commit
"drm/i915: Delay first PSR activation." move add the
delay workaround to the right place since all errors that
made us to introduce this delay here was the first
activation after the modeset.

So, now we are able to remove the delay on re-activation
getting better PSR residency.
