[PATCH 01/17] drm: Remove flag FBINFO_DEFAULT from fbdev emulation

The flag FBINFO_DEFAULT is 0 and has no effect, as struct fbinfo.flags
has been allocated to zero by framebuffer_alloc(). So do not set it.
Flags should signal differences from the default values. After cleaning
up all occurences of FBINFO_DEFAULT, the token can be removed.
