[PATCH 1/2] net: ethernet: mvneta: Do not error out in non serdes modes

[Sascha Hauer]

In mvneta_config_interface() the RGMII modes are catched by the default
case which is an error return. The RGMII modes are valid modes for the
driver, so instead of returning an error add a break statement to return
successfully.

This avoids this warning for non comphy SoCs which use RGMII, like
SolidRun Clearfog:

WARNING: CPU: 0 PID: 268 at drivers/net/ethernet/marvell/mvneta.c:3512
