    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().
