Check for ACPI resource conflicts in hwmon drivers. I've included
all Super-I/O and PCI drivers.
I've voluntarily left out:
* Vendor-specific drivers: if they conflicted on any system, this would
pretty much mean that they conflict on all systems, and we would know
by now.
* Legacy ISA drivers (lm78 and w83781d): they only support chips found
on old designs were ACPI either wasn't supported or didn't deal with
thermal management.
* Drivers accessing the I/O resources indirectly (e.g. through SMBus):
the checks are already done where they belong, i.e. in the bus drivers.
