Subject: [PATCH 1/3] net: stmmac: dwmac-sun8i: drop V3s compatible and add V3 one

The V3s is just a differently packaged version of the V3 chip, which has
a MAC with the same capability with H3. The V3s just doesn't wire out
the external MII/RMII/RGMII bus. (V3 wired out it).

Drop the compatible string of V3s in the dwmac-sun8i driver, and add a
V3 compatible string, which has all capabilities.

Signed-off-by: Icenowy Zheng <icenowy@...c.io>
