irda: fix !PNP support in drivers/net/irda/nsc-ircc.c
x86.git testing found the following build failure in latest -git:

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. ]
