[PATCH net-next v3 1/5] dt-bindings: net: rockchip-dwmac: Add compatible string for RK3528

[Jonas Karlman <jonas@kwiboo.se>]

Rockchip RK3528 has two Ethernet controllers based on Synopsys DWC
Ethernet QoS IP.

Add compatible string for the RK3528 variant.

Changes in v3:
- Rebase on latest net-next/main
- Collect r-b tag

Changes in v2:
- Restrict the minItems: 4 change to rockchip,rk3528-gmac

The enum will be extended in a future patch, Pending RK3562 and a future
RK3506 variant also only have 4 clocks.

Because snps,dwmac-4.20a is already listed in snps,dwmac.yaml adding the
rockchip,rk3528-gmac compatible did not seem necessary.
