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

efiboot/x86: eficons.c: Explicitly include params.h for howmany()

NFC for -current and netbsd-10, but necessary for netbsd-[89] to
pull up raw IO serial port support (PR port-amd64/57523).
