This fixes atyfb to not truncate 64 bits resources on 32 bits

returned to userspace via struct fb_fix_screeninfo. This will
have to be dealt with separately.

Not sure what that change gives us -- this function mostly treats 'addr'
as unsigned long (casting it to char/void *), ot compares it to 'unsigned
long' 'base' variable -- which should be made 'resource_size_t' in its turn
being assigned resource's start value. So, this part of patch looks incomplete
(and yet I'm not sure if SPARC really needs all that)...
