ibm_newemac: select CRC32 in Kconfig
The ibm_newemac driver requires ether_crc to be defined. Apparently it is
possible to generate a .config without CONFIG_CRC32 set which causes the
following link errors if IBM_NEW_EMAC is selected:
LD .tmp_vmlinux1
drivers/built-in.o: In function `emac_hash_mc':
core.c:(.text+0x2f524): undefined reference to `crc32_le'
core.c:(.text+0x2f528): undefined reference to `bitrev32'
make: *** [.tmp_vmlinux1] Error 1
This patch has IBM_NEW_EMAC select CRC32 so we don't hit this error.

This driver supports the IBM EMAC family of Ethernet controllers
typically found on 4xx embedded PowerPC chips, but also on the
