northbridge/intel/sandybridge: Enable x86_64 for mrc.bin

Enable x86_64 support for MRC.bin:
- Add a wrapper function for console printing that calls into
  long mode to call native do_putchar
- Remove Kconfig guard for x86_64 when MRC is being used

Tested: Booted Lenovo X220 using mrc.bin under x86_64 and
        MRC is able to print to the console.
