liteeth/mac: use native dw for LiteEthMACWishboneInterface 

This is required to support 64-bit wide data paths using the automatic
Wishbone bus width conversion as discussed in
enjoy-digital/liteeth#75. Otherwise, if the MAC data width deviates
from the 32-bit default set previously, received and transmitted
packets will be broken.
