irda: fix !PNP support in drivers/net/irda/nsc-ircc.c

x86.git testing found the following build failure in latest -git:

 drivers/built-in.o: In function `nsc_ircc_pnp_probe':
 nsc-ircc.c:(.text+0xdf1b6): undefined reference to `pnp_get_resource'

triggered via this config:

while generally most users will have PNP enabled, drivers can support
non-PNP build mode too - and most drivers implement it. That is typically
done by providing a dummy pnp_driver structure that will not probe anything.

The fallback routines in the driver will handle this dumber mode of
operation too.

This patch implements that. I have not tested whether this actually
works on real hardware so take care. It does resolve the build bug.

[ Another solution that is used by a few drivers is to exclude the driver
  in the Kconfig if PNP is disabled, via "depends on PNP", but this would
  limit the availability of the driver needlessly. ]
