Joe Hershberger 05b60ac549 net: phy: Clean up includes of common.h
We want to be able to include some other system headers in phy.h but
that requires us to have included common.h in the top-level first.

Also, common.h includes config.h as the first thing it does, so don't
include it directly.

Series-cc: Grygorii Strashko <grygorii.strashko@ti.com>
Seried-cc: ti
Series-process-log: sort, uniq
Cover-letter:
Prepare for net: phy: prevent uclass_eth device "node" field overwriting
Prepare for [1] so that it doesn't break the build for a bunch of
boards. There are a number of reasons this series broke the build
but none of them depend on changes in the series, so fix up those
situations ahead of applying that series.
