console: add support for QEMU's debugcon

Add support for sending debug output to an I/O port.

It can be used together with QEMU's isa-debugcon driver to log the
    coreboot output to a file.  The port is configurable and defaults
    to 0x402 which has established as the de facto standard. For example,
    SeaBIOS+OVMF [1] use that one too.
