XGI framebuffer supports big-endian machines, but it's currently
enabled based on __powerpc__ define (which is wrong, as powerpc can
be also little-endian now). Use __BIG_ENDIAN instead. This will fix
wrong colours on such machines.
Tested on parisc with XGI Z7.

The drivers/video directory is a mess. It contains generic video related
files, directories for backlight, console, linux logo, lots of fbdev
device drivers, fbdev framework files.
Make some order into the chaos by creating drivers/video/fbdev
directory, and move all fbdev related files there.
No functionality is changed, although I guess it is possible that some
subtle Makefile build order related issue could be created by this
patch.

The switch statement sets the temp value to zero for certain cases and
leaves it untouched for other cases -> all these other cases can be
combined in the default case.
Since an empty case containing only a break, it can be removed.
The patch also removes the if statement, as it uses the same value as the switch
for comparison, and includes the code into the switch.
