[PATCH] net: arc: select CRC32

[Vegard Nossum]

Fix the following build/link error by adding a dependency on the CRC32
routines:

  ld: drivers/net/ethernet/arc/emac_main.o: in function `arc_emac_set_rx_mode':
  emac_main.c:(.text+0xb11): undefined reference to `crc32_le'

The crc32_le() call comes through the ether_crc_le() call in
arc_emac_set_rx_mode().

Fixes: 775dd682e2b0ec ("arc_emac: implement promiscuous mode and multicast filtering")
