drm/radeon: Read the VRAM VBIOS signature with readb()
igp_read_bios_from_vram() checked bios[0]/bios[1] with a plain
__iomem load, which faults on sparc64 before the copy runs at all.
radeon_read_bios() already reads its two signature bytes with
readb() ahead of its own copy; use the same accessor here, keeping
the check before the allocation.
