drm/modes: parse_cmdline: Add support for named modes containing dashes
It is fairly common for named video modes to contain dashes (e.g.
"tt-mid" on Atari, "dblntsc-ff" on Amiga). Currently such mode names
are not recognized, as the dash is considered to be a separator between
mode name and bpp.
Fix this by skipping any dashes that are not followed immediately by a
digit when looking for the separator.
