Merge branch 'Qualcomm-ethqos'

Vinod Koul says:

====================
net: Add support for Qualcomm ethqos

Some Qualcomm SoCs sport a ethqos controller which use DW ip, so add
the glue driver which uses stmmac driver along with DT bindings for
this device.

This controller supports rgmii mode and doesn't work with existing
phy drivers as they do not remove the phy delay delay in this mode,
so fix the two phy drivers tested with this.

Changes in v3:
 - Add description in DT and rename the file and compatible as suggested by
   Rob
 - Update changelog for QCA8K driver
 - Update AT803x phy disable delay for all RGMxx modes

Changes in v2:
 - Fix the example in dt-binding
 - Remove DT property for disable the delay and disable delay for RGMII mode
   in AT803x and QCA8K PHY drivers
