[PATCH net-next v2 4/5] net: dt-bindings: Introduce the Qualcomm IPQESS Ethernet controller

[Maxime Chevallier <maxime.chevallier@bootlin.com>]

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.

V1->V2:
 - Fixed the example
 - Added reset and clocks
 - Removed generic ethernet attributes
