Subject: [PATCH 03/17] fbdev: Remove flag FBINFO_DEFAULT from fbdev drivers

The flag FBINFO_DEFAULT is 0 and has no effect, as struct fbinfo.flags
has been allocated to zero by kzalloc(). 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.
