b24413180f ("License cleanup: add SPDX GPL-2.0 license identifier to
files with no license") added SPDX GPL-2.0 to several PCI files that
previously contained no license information.
Add SPDX GPL-2.0 to all other PCI files that did not contain any license
information and hence were under the default GPL version 2 license of the
kernel.

The PCI endpoint test driver uses crc32_le() so it should select
CRC32. Fixes this build error (when CRC32=m):
drivers/built-in.o: In function `pci_epf_test_cmd_handler':
pci-epf-test.c:(.text+0x2d98d): undefined reference to `crc32_le'
