[PATCH v2 09/16] x86: coreboot: Use a memory-mapped UART

Simon Glass sjg at chromium.org

This is much more common on modern hardware, so default to using it.

This does not affect the normal UART, but does allow the debug UART to
work, since it uses serial_out_shift(), etc.

Changes in v2:
- Expand commit message to explain this is for the debug UART
- Update the defconfig instead
