Bjorn Helgaas 8cfab3cf63 PCI: Add SPDX GPL-2.0 to replace GPL v2 boilerplate 
Add SPDX GPL-2.0 to all PCI files that specified the GPL version 2 license.

Remove the boilerplate GPL version 2 language, relying on the assertion in
b24413180f ("License cleanup: add SPDX GPL-2.0 license identifier to
files with no license") that the SPDX identifier may be used instead of the
full boilerplate text.

David Woodhouse f719582435 PCI: Add pci_mmap_resource_range() and use it for ARM64 
Starting to leave behind the legacy of the pci_mmap_page_range() interface
which takes "user-visible" BAR addresses.  This takes just the resource and
offset.

For now, both APIs coexist and depending on the platform, one is
implemented as a wrapper around the other.
