lantiq: xrx200: replace patch with upstream version

This commit replaces patch number 0703 with the upstream accepted
version. This patch requires backporting an additional patch to
avoid conflicts.

The only significant change is the lower maximum MTU. Packets with
lengths over 2400 may be dropped.

+Subject: [PATCH] net: dsa: lantiq: allow to use all GPHYs on xRX300 and xRX330
+
+This patch allows to use all PHYs on GRX300 and GRX330. The ARX300
+has 3 and the GRX330 has 4 integrated PHYs connected to different
+ports compared to VRX200. Each integrated PHY can work as single
+Gigabit Ethernet PHY (GMII) or as double Fast Ethernet PHY (MII).
+
+Allowed port configurations:
+
+xRX200:
+GMAC0: RGMII, MII, REVMII or RMII port
+GMAC1: RGMII, MII, REVMII or RMII port
+GMAC2: GPHY0 (GMII)
+GMAC3: GPHY0 (MII)
+GMAC4: GPHY1 (GMII)
+GMAC5: GPHY1 (MII) or RGMII port
+
+xRX300:
+GMAC0: RGMII port
+GMAC1: GPHY2 (GMII)
+GMAC2: GPHY0 (GMII)
+GMAC3: GPHY0 (MII)
+GMAC4: GPHY1 (GMII)
+GMAC5: GPHY1 (MII) or RGMII port
+
+xRX330:
+GMAC0: RGMII, GMII or RMII port
+GMAC1: GPHY2 (GMII)
+GMAC2: GPHY0 (GMII)
+GMAC3: GPHY0 (MII) or GPHY3 (GMII)
+GMAC4: GPHY1 (GMII)
+GMAC5: GPHY1 (MII), RGMII or RMII port
+
+Tested on D-Link DWR966 (xRX330) with OpenWRT.
