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'
Fixes: 349e7a85b25f ("PCI: endpoint: functions: Add an EP function to test PCI")
