pldmfw: Select CRC32 when PLDMFW is selected

[ Upstream commit 1224b218a4b9203656ecc932152f4c81a97b4fcc ]

pldmfw calls crc32 code and depends on it being enabled, else
there is a link error as follows. So PLDMFW should select CRC32.

  lib/pldmfw/pldmfw.o: In function `pldmfw_flash_image':
  pldmfw.c:(.text+0x70f): undefined reference to `crc32_le_base'

This problem was introduced by commit b8265621f488 ("Add pldmfw library
for PLDM firmware update").

It manifests as of commit d69ea414c9b4 ("ice: implement device flash
update via devlink").

And is more likely to occur as of commit 9ad19171b6d6 ("lib/crc: remove
unnecessary prompt for CONFIG_CRC32 and drop 'default y'").

Found by chance while exercising builds based on tinyconfig.
