parport_pc: Fix build failure drivers/parport/parport_pc.c for powerpc

In commit 51dcdfec6a274afc1c6fce180d582add9ff512c0 ("parport: Use the
PCI IRQ if offered") parport_pc_probe_port() gained an irqflags arg.
This isn't being supplied on powerpc. This patch make powerpc fallback
to the old behaviour, that is using "0" for irqflags.

Fixes build failure:
