Merge branch 'bcmgenet-add-support-for-GENETv5'

Doug Berger says:

====================
net: bcmgenet: add support for GENETv5

This collection of patches contains changes related to adding
support for the BCM7260, BCM7268, and BCM7271 devices that
contain a new version of the GENET MAC IP block (v5) and a new
fast ethernet (10/100BASE-T) internal PHY.

These patches were originally developed on top of the bug fixes
of the "[PATCH v2 net 0/8] net: bcmgenet: minor bug fixes" patch
set previously accepted into the net repository, but this
submission is designed to be applied to the current net-next
that does not yet include them. As a result there will be some
merge conflicts that I would be happy to help resolve if desired.

Specifically, conflicts should occur with these patches from the
minor bug fixes set:
[PATCH v2 net 3/8] net: bcmgenet: reserved phy revisions must be checked first
[PATCH v2 net 5/8] net: bcmgenet: synchronize irq0 status between the isr and task
[PATCH v2 net 8/8] net: bcmgenet: decouple flow control from bcmgenet_tx_reclaim
====================
