    ptp_pch: Replace deprecated PCI functions

    pcim_iomap_regions() and pcim_iomap_table() have been deprecated in
    commit e354bb8 ("PCI: Deprecate pcim_iomap_table(),
    pcim_iomap_regions_request_all()").

    Replace these functions with pcim_iomap_region().

    Additionally, pass KBUILD_MODNAME to that function, since the 'name'
    parameter should indicate who (i.e., which driver) has requested the
    resource.
