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") Co-developed-by: Edmund Dea <edmund.j.dea@intel.com> Signed-off-by: Edmund Dea <edmund.j.dea@intel.com> Signed-off-by: Anitha Chrisanthus <anitha.chrisanthus@intel.com> Acked-by: Sam Ravnborg <sam@ravnborg.org> Link:https://patchwork.freedesktop.org/patch/msgid/20211013233632.471892-2-anitha.chrisanthus@intel.com Signed-off-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>
