Subject: [PATCH-next] intel ethernet: fix s390 build failure due to implicit prefetch.h

As of commit 7f12ad741a4870b8b6e3aafbcd868d0191770802 ("i40evf: transmit
and receive functionality") the s390 builds (allyesconfig) fail with:

drivers/net/ethernet/intel/i40evf/i40e_txrx.c: In function 'i40e_clean_rx_irq':
drivers/net/ethernet/intel/i40evf/i40e_txrx.c:818:3: error: implicit declaration of function 'prefetch'
make[5]: *** [drivers/net/ethernet/intel/i40evf/i40e_txrx.o] Error 1

due to an implicit assumption that the prototype from linux/prefetch.h
will be present.
