ata: pata_macio: Fix PCI region leak

pci_request_regions() became a managed devres functions if the PCI
device was enabled with pcim_enable_device(), which is the case for
pata_macio.

The PCI subsystem recently removed this hybrid feature from
pci_request_region(). When doing so, pata_macio was forgotten to be
ported to use pcim_request_all_regions(). If that function is not used,
pata_macio will fail on driver-reload because the PCI regions will
remain blocked.

Fix the region leak by replacing pci_request_regions() with its managed
counterpart, pcim_request_all_regions().
