[PATCH v1] ARM: zynq: Fix earlyprintk in big endian mode

earlyprintk messages are not appearing on the terminal
emulator during a big endian kernel boot. If we
byte swap the sending data it comes properly.

This can be tested by adding 'early_print("early print test\n");'
to setup_arch() in arch/arm/kernel/setup.c
