Subject: [PATCH net-next v8 1/5] net: dt-bindings: Introduce the Qualcomm IPQESS Ethernet controller
Add the DT binding for the IPQESS Ethernet Controller. This is a simple
controller, only requiring the phy-mode, interrupts, clocks, and
possibly a MAC address setting.

V2->V3:
- Cleanup on reset and clock names
V1->V2:
- Fixed the example
- Added reset and clocks
- Removed generic ethernet attributes
