[PATCH] PCI Hotplug: Better reporting of PCI frequency / bus mode problems for acpi driver

When plugging a 33MHz card into a bus that's running at 66MHz, I'd like
to see a better error message than:

acpiphp_glue: notify_handler: unknown event type 0x5 for \_SB_.SBA0.PCI4.S2F0

The following patch would give us:

Device \_SB_.SBA0.PCI4.S2F0 cannot be configured due to a frequency mismatch

which I think is clearer.
