[PATCH v2 2/6] drm/udl: fix Bpp calculation in dumb_create()

[David Herrmann <dh.herrmann@gmail.com>]

Probably a typo.. we obviously need "(bpp + 7) / 8" instead of
"(bpp + 1) / 8". Unlikely to be hit in any sane code, but lets be safe.
Use DIV_ROUND_UP() to avoid the problem entirely and make the core more
readable.
