Commit Message

After commit 171a9bae68c7 ("staging/octeon: Allow test build on
!MIPS"), the following combination of configs cause a few Kconfig
warnings and build errors (distilled from arm allyesconfig and Randy's
randconfig builds):

    CONFIG_NETDEVICES=y
    CONFIG_STAGING=y
    CONFIG_COMPILE_TEST=y

and CONFIG_OCTEON_ETHERNET as either a module or built-in.

WARNING: unmet direct dependencies detected for MDIO_OCTEON
  Depends on [n]: NETDEVICES [=y] && MDIO_DEVICE [=y] && MDIO_BUS [=y]
&& 64BIT [=n] && HAS_IOMEM [=y] && OF_MDIO [=n]
  Selected by [y]:
  - OCTEON_ETHERNET [=y] && STAGING [=y] && (CAVIUM_OCTEON_SOC ||
COMPILE_TEST [=y]) && NETDEVICES [=y]

In file included from ../drivers/net/phy/mdio-octeon.c:14:

      |                                    ^~~~~~

CONFIG_64BIT is not strictly necessary if the proper readq/writeq
definitions are included from io-64-nonatomic-lo-hi.h.

CONFIG_OF_MDIO is not needed when CONFIG_COMPILE_TEST is enabled because
of commit f9dc9ac51610 ("of/mdio: Add dummy functions in of_mdio.h.").

Fixes: 171a9bae68c7 ("staging/octeon: Allow test build on !MIPS")

v1 -> v2:

* Address Randy's reported failure here: https://lore.kernel.org/netdev/b3444283-7a77-ece8-7ac6-41756aa7dc60@infradead.org/
  by not requiring CONFIG_OF_MDIO when CONFIG_COMPILE_TEST is set.

* Improve commit message

Sorry for the confusion, I'll do my best to add a patch suffix in the
future.

Thank you for picking this up!
