Link training should be enabled in the driver probe for root port mode.
We should not have to wait for transport to be loaded for this to

bridge side of the link.

This patch only moves files to their new locations, before applying the
next two patches adding the NTB Abstraction layer. Splitting this patch
from the next is intended make distinct which code is changed only due
to moving the files, versus which are substantial code changes in adding
the NTB Abstraction layer.
