Tested on mx51 babbage.  The non-dt kernel works fine, but dt kernel
does not.

I tracked it down a little bit and found, before calling kernel from
arch/arm/boot/compressed/head.S, the dtb magic number (at address
pointed by r8) was interpolated to 0x73fbc000 which happens to be the
value of 'uart_base' assigned in plat-mxc/include/mach/uncompress.h.
