net: pxa168: Fix build errors by including interrupt.h

I saw a recent patch that moves pxa168_eth.c to ethernet/marvell.
I still hope my patch is useful as I didn't any patch fixing these
build errors. Please ignore if it's already fixed somewhere.

Thanks,
Tanmay

Commit a6b7a407865aab9f849dd99a71072b7cd1175116 removed
linux/interrupt.h from netdevice.h. This fixes below build failure
