Log Message:
efiboot/x86: Add serial console support via raw I/O port access

Unfortunately, some (most?) UEFI implementations do not support
com ports by ``Serial I/O Protocol''.

``PNP0501-0'' and friends are not recognized also.

In this case, if user explicitly requires to switch to serial
console by ``consdev'' command, try to use raw I/O port access.

Ugly, but what FreeBSD does, at least.

Proposed as PR port-amd64/57523
