I think this begs an even more fundamental question, why isn't the PTP
driver abstraction providing the necessary methods and interfaces so
that pch_gbe doesn't have to call into the ptp_pch.c code directly?

Moving ptp_pch.c elsehwere is not desirable, it's a PTP driver so
it belongs under drivers/ptp.

Someone who understands all of these components needs to sort this
out cleanly, this patch isn't it.
