drm: Always warn if user-defined modes are not supported

Browse source

Print a warning if a user-specifed display mode is not supported by
the display pipeline. Users specified the display mode on the kernel
command line with the use of the video= parameter. Setting an
unsupported mode will leave the console blank, so we should at least
let the user know why.
