This patch requires Stefano's driver for MX5/MX6.
	http://lists.denx.de/pipermail/u-boot/2012-February/118530.html

V2 updated based on comments from the ML:
	- uses data structures imx_ccm_reg and iomuxc_base_regs 
	for register offsets and constants from imx-regs.h and iomux-v3.h
	- moves setup_sata() from board_early_init_f() into board_init()
