Re: [PATCH -next] net: hisilicon: Never build on SPARC

The Hisilicon network driver does not build for Sparc. Enabling
COMPILE_TEST for it causes Sparc allmodconfig/allyesconfig builds
to fail with

drivers/net/ethernet/hisilicon/hns_mdio.c: In function 'hns_mdio_bus_name':
drivers/net/ethernet/hisilicon/hns_mdio.c:409:3: error:
		implicit declaration of function 'of_translate_address'

I wish we would really resolve this properly instead of hacking crap
like this all the time, it's stupid.

SPARC simply never needs to "translate" OF addresses, since all OF
resources are fully translated already at boot time during OF tree
import.

All IRQs are fully resolved as well.

So we could simply make of_translate_address() a NOP.
