Add devicetree binding document for Loongson-1 DWMAC glue layer.
Signed-off-by: Keguang Zhang <keguang.zhang@gmail.com>
---
V1 -> V2: Fix "clock-names" and "interrupt-names" property
Rename the syscon property to "loongson,dwmac-syscon"
Drop "phy-handle" and "phy-mode" requirement
Revert adding loongson,ls1b-dwmac/loongson,ls1c-dwmac
to snps,dwmac.yaml
