[PATCH net-next v3 1/5] dt-bindings: net: sun8i-emac: Add A733 GMAC210 compatible

The A733 GMAC210 is a DesignWare MAC 5.20 close to the A523 GMAC200, with
the following differences:
* The glue configuration registers are a dedicated MMIO region of the
controller instead of a syscon register, so a second reg entry replaces
the syscon phandle.
* The DMA channels and the LPI event have their own interrupt lines.
* A PTP reference clock and an AHB reset are needed.
* Unlike the A523, the controller does not appear to belong to a power
domain.
* The TX clock delay field is 5 bits wide and both TX and RX delays use a
180ps step, allowing up to 5580ps.
Add the new compatible and describe those differences. Declare the internal
delay properties at the top level and keep their limits per compatible.
