[PATCH] pci: endpoint: fix endpoint test build error

[Randy Dunlap]

From: Randy Dunlap <rdunlap@xxxxxxxxxxxxx>

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).
