cc1: some warnings being treated as errors
This allows MDIO_OCTEON to be built with COMPILE_TEST as well and
includes the proper header for readq/writeq. This does not address
the several -Wint-to-pointer-cast and -Wpointer-to-int-cast warnings
that appeared as a result of commit 171a9bae68c7 ("staging/octeon:
Allow test build on !MIPS") in these files.
