mcb: mcb-pci: detect IO mapped devices before requesting resources
If the memory region is requested with devm_request_mem_region()
for an IO mapped device it will return an error and mcb-pci will
incorrectly report it with EBUSY code.
Make sure we identify if the reosure is IO mapped and fail early
with a correct ENOTSUPP code.
