[PATCH] pm2fb: fix fbi image display on 24 bit depth big endian

Handle 24bit on big-endian by leaving the hardware in RGB and using the
colour offset to reverse red/blue.  Leaving the hardware in RGB means that
fbi displays images correctly (abeit fortuitously) and the console is
correct, thanks to a recent patch to the console code correcting an endian
bug in fbcon_putc().
