[PATCH 1/3] radeonfb: Fix 64 bits resources on 32 bits archs

[Benjamin Herrenschmidt <benh@kernel.crashing.org>]

This fixes radeonfb to not truncate 64 bits resources on 32 bits
platforms. Unfortunately, there are still issues with addresses
returned to userspace via struct fb_fix_screeninfo. This will
have to be dealt with separately.
