Merge branch 'dpaa2-eth-small-cleanup'

Ioana Ciornei says:

====================
dpaa2-eth: small cleanup

These 3 patches are just part of a small cleanup on the dpaa2-eth and
the dpaa2-switch drivers.

In case we are hitting a case in which the fwnode of the root dprc
device we initiate a deferred probe. On the dpaa2-switch side, if we are
on the remove path, make sure that we check for a non-NULL pointer
before accessing the port private structure.
