video: fbdev: Check Standard Timing against DMT
Add the VESA Display Monitor Timing (DMT) table. During parsing of Standard Timings, it compare the 2 byte STD code with DMT to see what the VESA mode should be. If there is no entry in the vesa_modes table or no match found, it fallsback to the GTF timings. Signed-off-by: David Ung <davidu@nvidia.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
