[PATCH] ptp_pch: Replace deprecated PCI functions

[Philipp Stanner <pstanner@redhat.com>]

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().

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