[PATCH 4/8] video/aperture: Only kick vgacon when the pdev is decoding vga

[Daniel Vetter]

Otherwise it's bit silly, and we might throw out the driver for the
screen the user is actually looking at. I haven't found a bug report
for this case yet, but we did get bug reports for the analog case
where we're throwing out the efifb driver.

v2: Flip the check around to make it clear it's a special case for
kicking out the vgacon driver only (Thomas)
