[PATCH] hw/mips/jazz: Map the UART devices unconditionally

[Philippe Mathieu-Daudé]

When using the Magnum ARC firmware we can see accesses to the
UART1 beeing 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 there
are character devices connected, map them unconditionally.
