 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
