Subject: soc/intel/skylake: Add support to print ME version

This change adds a boot state callback to print ME version after
DEV_ENABLE is complete. Information is printed only if UART_DEBUG is
enabled because talking to ME to get the firmware version adds ~1
second to boot time.

TEST=Verified on Soraka that ME version printed is correct.
