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")

PCI: endpoint: functions: Add an EP function to test PCI2017-04-11T19:18:37+00:00Kishon Vijay Abraham Ikishon@ti.com2017-03-27T09:45:03+00:00urn:sha1:349e7a85b25fa6ee82902d9be2cc5f3bec815120
Adds a new endpoint function driver (to program the virtual test device)
making use of the EP-core library.

Introduce a new configfs entry to configure the EP function (like
configuring the standard configuration header entries) and to bind the EP
function with EP controller.

Introduce a new EP core layer in order to support endpoint functions in
linux kernel. This comprises the EPC library (Endpoint Controller Library)
and EPF library (Endpoint Function Library). EPC library implements
functions specific to an endpoint controller and EPF library implements
functions specific to an endpoint function.
