drm/amd/display: update NV12/NV21 as the YUV format

This patch updates the YUV format supported to
NV12 and NV21 and hence updates the offsets.

BUG: SWDEV-119421
TEST: (On Chromium OS for Stoney Only)
    * Executed below tests to see YUV(underlay) & RGB planes on eDP
    plane_test --format XR24 --size 500x100 -p --format NV12 --size
    500x500
