[PATCH v2 2/3] dt-bindings: net: meson-dwmac: add T7 support

[Xianwei Zhao via B4 Relay]

From: Xianwei Zhao <xianwei.zhao at amlogic.com>

Add the T7 compatible to the Meson DWMAC binding.

The T7 DWMAC controller requires the following compatible combination:

amlogic,t7-dwmac
amlogic,meson-axg-dwmac
snps,dwmac-4.00

Add a conditional schema check to enforce this compatible combination
when amlogic,t7-dwmac is used.
