Merge branch 'mvpp2-add-TX-interrupts-support'

Thomas Petazzoni says:

====================
net: mvpp2: add TX interrupts support

So far, the mvpp2 driver was using an hrtimer to handle TX
completion. This patch series adds support for using TX interrupts
(for each CPU) on PPv2.2, the variant of the IP used on Marvell Armada
7K/8K.

Dave: this version can be applied right away, it no longer depends on
Antoine's patch series. Antoine series had some comments, so he will
have to respin later on. Therefore, let's merge this smaller patch
series first.

Changes since v1:

 - Rebased on top of net-next, instead of on top of Antoine's series.

 - Removed the Device Tree patch, as it shouldn't go through the net
   tree.
====================
