drm/i915/display: Fix mode private_flags comparison at atomic_check
This patch fixes the private_flags of mode to be checked and
compared against uapi.mode and not from hw.mode. This helps
properly trigger modeset at boot if desired by driver.
It helps resolve audio_codec initialization issues if display
is connected at boot. Initial discussion on this issue has happened
on below thread:
https://patchwork.freedesktop.org/series/74828/
v2: No functional change. Fixed the Closes tag and added
Maarten's RB.
v3: Added Fixes tag.
