net: Move network rules to drivers/netWIP/2021-09-04-makefile-cleanups-part-b

The code under drivers/net is related to ethernet networking drivers, in
some fashion or another.  Drop these from the top-level Makefile and
also move the phy rule into drivers/net/Makefile which is where it
belongs.  Make the new rule for drivers/net check for the build-stage
relevant ETH symbol.

Fix up some Kconfig dependencies while we're here to mirror how the
Makefile logic now works.
