drm: move native byte order quirk to new drm_driver_legacy_fb_format function
Turns out we need the pixel format fixup not only for the addfb ioctl,
but also for fbdev emulation code.
Ideally we would place it in drm_mode_legacy_fb_format(). That would
create alot of churn though, and most drivers don't care because they
never ever run on a big endian platform. So add a new
drm_driver_legacy_fb_format() function instead which looks at the
mode_config->quirk_addfb_prefer_host_byte_order flag.
