Michael Brown 595ff24030 [spcr] Add support for the ACPI Serial Port Console Redirection table ...

The BIOS may provide an ACPI Serial Port Console Redirection (SPCR)
table to describe the serial port to be used for early boot messages.

Add support for parsing the SPCR and instantiating a 16550-based UART.
We do not currently attempt to support other types of UART, since iPXE
does not yet have drivers for other types.
