dt-bindings: net: mediatek: add support for MediaTek MT7623 and MT7622 SoC

Browse source 
The patch adds the supplements in the dt-binding document for MediaTek
MT7622 SoC with extra SGMII system controller and relevant clock consumers
listed as the requirements for those SoCs equipped with the SGMII circuit.
Also, add the missing binding information for MT7623 SoC here which relies
on the fallback binding of MT2701.

- reg: Address and length of the register set for the device
- interrupts: Should contain the three frame engines interrupts in numeric
order. These are fe_int0, fe_int1 and fe_int2.
- clocks: the clock used by the core
- clock-names: the names of the clock listed in the clocks property. These are

- resets: Should contain a phandle to the ethsys reset signal
- reset-names: Should contain the reset signal name "eth"
- mediatek,ethsys: phandle to the syscon node that handles the port setup
- mediatek,sgmiisys: phandle to the syscon node that handles the SGMII setup
which is required for those SoCs equipped with SGMII such as MT7622 SoC.
- mediatek,pctl: phandle to the syscon node that handles the ports slew rate
and driver current
Optional properties:
