[PATCH 10/21] drm/amd/display: Reduce SCDC Status Flags Definition

[Solomon Chiu <solomon.chiu@amd.com>]

From: Chris Park <chris.park@amd.com>

[Why]
Status flags definition is reduced to read
less bytes in SCDC transaction for status update.

[How]
Reduce definition of reserved bytes from 3 to 1
for status update.
