lan78xx: select CRC32

[ Upstream commit 46393d61a328d7c4e3264252dae891921126c674 ]

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

  ld: drivers/net/usb/lan78xx.o: in function `lan78xx_set_multicast':
  lan78xx.c:(.text+0x48cf): undefined reference to `crc32_le'

The actual use of crc32_le() comes indirectly through ether_crc().
