gpio: pcie-idio-24: Replace deprecated PCI functions

pcim_iomap_regions() and pcim_iomap_table() have been deprecated in
commit e354bb84a4c1 ("PCI: Deprecate pcim_iomap_table(),
pcim_iomap_regions_request_all()"). Replace these functions with
pcim_iomap_region().

In order to match the rest of the code in idio_24_probe(), utilize
dev_err_probe() to handle error for pcim_enable_device().
