[PATCH] drm/amd/display: simplify FreeSync MCCS capability check

[Avi Radinsky]

Simplify the FreeSync MCCS capability check by removing a redundant
freesync_vcp_code test. The expression matches Coccinelle's
!A || (A && B) to !A || B simplification without changing behavior.

Fixes: 6f71d5dd3206 ("drm/amd/display: Read sink freesync support via mccs")
