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

The offb_init_palette_hacks() routine also made assumption on the

This patch simply changes the name of the variable from "bhrb_filter" to
"bhrb_hw_filter" in order to add one more variable which will track SW
filters in generic powerpc book3s code which will be implemented in the
subsequent patch.
