Bjorn Helgaas 172d0496cd PNP SMCf010 quirk: auto-config device if BIOS left it broken
Some HP firmware leaves the SMCf010 IRDA device incompletely configured, or
reports the wrong resources in _CRS.  As a workaround, when we find such a
device, try to auto-configure the device.

This ignores the _CRS data, picks a config from _PRS, and runs _SRS to
configure the device.  This makes smsc-ircc2 work correctly with PNP
resources (with no preconfiguration!) on all the machines I tested.

I think Windows does something like this by default for all devices,
so we should consider doing the same thing in Linux.

This patch addresses part of the 2.6.22 regression:
    "no irda0 interface (2.6.21 was OK), smsc does not find chip"
It fixes smsc-ircc2 PNP device detection on HP nc6000, nc6220, nw8000,
nw8240, and possibly other machines.
