[PATCH v2] offb: make the screen properties endian safe

["Cédric Le Goater" <clg@fr.ibm.com>]

The "screen" properties : depth, width, height, linebytes need
to be converted to the host endian order when read from the device
tree.

Changes in v2:

 - replaced be32_to_cpu() by be32_to_cpup() 
 - fixed setcolreg ops
