PCI: Add SPDX GPL-2.0 to replace GPL v2 boilerplate ...

Port of a Linux commit 8cfab3c

  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
  b24413180f56 ("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.

Besides the functional driver itself, it also adds SoC specific PHY
setup required for PCIe. Currently, only Armada 370 is fully supported.
