drm/gma500: Clear fbdev framebuffer with fb_memset_io() 

The fbdev framebuffer is I/O memory, so clear it with fb_memset_io().
Fixes the following sparse warning:

../drivers/gpu/drm/gma500/fbdev.c:234:20: warning: incorrect type in argument 1 (different address spaces)
../drivers/gpu/drm/gma500/fbdev.c:234:20:    expected void *s
../drivers/gpu/drm/gma500/fbdev.c:234:20:    got char [noderef] __iomem *screen_base
