x86, earlyprintk: Add hsu early console for Intel Medfield platform
Intel Medfield platform has a high speed UART device, which
could act as a early console. To enable early printk of HSU
console, simply add "earlyprintk=hsu" in kernel command line.
Currently we put the code in the early_printk_mrst.c as it is
also for Intel MID platforms like the mrst early console
