Remove 6 unused extern variables to reduce confusion. It is worth
mentioning that lib/fonts/font_8x8.c and lib/fonts/font_8x16.c also
declare `fontdata_8x8` and `fontdata_8x16` respectively, and this file
has nothing to do with them.

This was unused ever since this driver was merged into 2.1.67 (I looked at
historical linux git trees quickly). Save to delete I'd say, probably just
copypasted from some outdated driver template that was even older.

Applied to drm-misc-next.
