serial: 8250: bind to ALi Fast Infrared Controller (ALI5123)

commit 1d7002777a8fe8188caaa98d4a8eb4ed298fcdae upstream.

This way this device can be used with irtty-sir -
at least on Toshiba Satellite A20-S103 it is not configured by default
and needs PNP activation before it starts to respond on I/O ports.

This device has actually its own driver (ali-ircc),
but this driver seems to be non-functional for a very long time

[bwh: Backported to 3.2:
 - Drop change to acpi_pnp.c, as there's no need to whitelist ACPI devices
   for the PNP bus
 - Adjust filename]
