Use DRM_FORMAT_HOST_XRGB8888, so we are using the correct format code on bigendian machines. Also set the quirk_addfb_prefer_host_byte_order mode_config bit so drm_mode_addfb() asks for the correct format code. Create our own plane and use drm_crtc_init_with_planes() instead of depending on the default created by drm_crtc_init(). That way the plane format list is correct on bigendian machines. Also re-add the framebuffer format check dropped by "df2052cc92 bochs: convert to drm_fb_helper_fbdev_setup/teardown". With this patch applied both ADDFB and ADDFB2 ioctls work correctly in the bochs-drm.ko driver on big endian machines. Without the patch only ADDFB (which still seems to be used by the majority of userspace) works correctly.
