phy: dp83640: select CONFIG_CRC32

Browse Source 
commit f9d6f94132f01d2a552dcbab54fa56496638186d upstream.

Without crc32, this driver fails to link:

arm-linux-gnueabi-ld: drivers/net/phy/dp83640.o: in function `match':
dp83640.c:(.text+0x476c): undefined reference to `crc32_le'

Fixes: 539e44d26855 ("dp83640: Include hash in timestamp/packet matching")
