The HNS MDIO driver fails to build on older ARM machines that are not
yet converted to CONFIG_OF:
drivers/net/ethernet/hisilicon/hns_mdio.c: In function 'hns_mdio_bus_name':
drivers/net/ethernet/hisilicon/hns_mdio.c:405:14: error: 'OF_BAD_ADDR'
undeclared (first use in this function)
u64 taddr = OF_BAD_ADDR;
^
drivers/net/ethernet/hisilicon/hns_mdio.c:405:14: note: each undeclared
identifier is reported only once for each function it appears in
drivers/net/ethernet/hisilicon/hns_mdio.c:409:11: error: implicit declaration
of function 'of_translate_address' [-Werror=implicit-function-declaration]
taddr = of_translate_address(np, addr);
^
This clarifies the dependency to ensure we don't attempt to build these
drivers without CONFIG_OF, but also adds a COMPILE_TEST alternative to
give us better build coverage testing.
Build-tested on x86 as well to ensure this actually works.

If you have a network (Ethernet) card belonging to this class, say Y.
