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.
