Add qedr

Add all of the qedr patches from linux-next v4.8 until:
e4917d46a653 qede: Add aRFS support

All qed and qede patches along the way were updated as well as
qedr must be synchronized with them. Still these patches were
dropped:
054c67d1c82a qed*: Add support for ethtool link_ksettings callbacks.
16d5946a7c96 qede: Fix forcing high speeds
d7455f6e4450 qede: Decouple ethtool caps from qe
