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.

V7->V8:
 - No changes
V6->V7:
 - Fixed a typo (firts -> first)
V5->V6:
 - Fixed the $id that used the wrong compatible
 - Force passing all the per-queue interrupts
V4->V5:
 - Remove stray quotes arount the ref property
 - Rename the binding to match the compatible string
V3->V4:
 - Fix a binding typo in the compatible string
V2->V3:
 - Cleanup on reset and clock names
V1->V2:
 - Fixed the example
 - Added reset and clocks
 - Removed generic ethernet attributes
