[0/2] video: A couple of fixes for the vga16fb driver

This patch series contains two fixes for the vga16fb driver. I looked at
the driver due a regression reported [0], caused by commit d391c5827107
("drivers/firmware: move x86 Generic System Framebuffers support").

The mentioned commit didn't change any logic but just moved the platform
device registration that matches the vesafb and efifb drivers to happen
later. And this caused the vga16fb driver to be probed even in machines
that don't have an EGA or VGA video adapter.

Patch #1 is fixing the wrong check to determine if either EGA or VGA is
used and patch #2 adds a check to the driver to only be loaded for EGA
and VGA 16 color graphic cards.
