When using the Magnum ARC firmware we can see accesses to the
UART1 being rejected, because the device is not mapped:
$ qemu-system-mips64el -M magnum -d guest_errors,unimp -bios NTPROM.RAW
Invalid access at addr 0x80007004, size 1, region '(null)', reason: rejected
Invalid access at addr 0x80007001, size 1, region '(null)', reason: rejected
Invalid access at addr 0x80007002, size 1, region '(null)', reason: rejected
Invalid access at addr 0x80007003, size 1, region '(null)', reason: rejected
Invalid access at addr 0x80007004, size 1, region '(null)', reason: rejected
Since both UARTs are present (soldered on the board) regardless
of whether there are character devices connected, map them
unconditionally.
