ide-generic: handle probing of legacy io-ports v5

Avoid probing the io-ports in case an IDE PCI controller is present and it
uses the legacy iobases. If we still want to enforce the probing, we do

ide_generic.probe_mask=0x3f

on the kernel command line. The iobase checking code is
adapted from drivers/ata/pata_legacy.c after converting hex
pci ids into their corresponding macros in <linux/pci_ids.h>.

Also, check only BAR0/2 resources since those are guaranteed
by the workaround in drivers/pci/probe.c:pci_setup_device().
