ARM: imx: enable big endian mode
Enable ARM big-endian mode on mach-imx. This requires adding some
byte swapping in the debug functions (which otherwise hang forever)
and of course the secondary core bringup.
Tested (on top of 4.4) on i.MX6 HummingBoard quad-core (IMX6Q).
The patch is pretty much as suggested by Arnd Bergmann, thanks!
