drm/kmb: Limit supported mode to 1080p
KMB only supports single resolution(1080p), this commit checks for
1920x1080x60 or 1920x1080x59 in crtc_mode_valid.
Also, modes with vfp < 4 are not supported in KMB display. This change
prunes display modes with vfp < 4.
v2: added vfp check
Fixes: 7f7b96a8a0a1 ("drm/kmb: Add support for KeemBay Display")
