Kristian H. Kristensen 47a66e45d7 drm: Only use compat ioctl for addfb2 on X86/IA64
Similar to struct drm_update_draw, struct drm_mode_fb_cmd2 has an
unaligned 64 bit field (modifier). This get packed differently between
32 bit and 64 bit modes on architectures that can handle unaligned 64
bit access (X86 and IA64).  Other architectures pack the structs the
same and don't need the compat wrapper. Use the same condition for
drm_mode_fb_cmd2 as we use for drm_update_draw.

Note that only the modifier will be packed differently between compat
and non-compat versions.
