fbdev/atafb: Remove flag FBINFO_FLAG_DEFAULT

The flag FBINFO_FLAG_DEFAULT is 0 and has no effect, as struct
fbinfo.flags has been allocated to zero by a static declaration. So do
not set it.

Flags should signal differences from the default values. After cleaning
up all occurrences of FBINFO_DEFAULT, the token will be removed.

v2:
	* fix commit message (Miguel)
