ramips: fix up switch settings for Sitecom WL-351 v1 002
Pinmux for rgmii needs to be set to rgmii, not gpio. Hide the ESW switch on boot (using new rgmii esw devicetree attribute). Also add a Sitecom-specific profile, since the image needs to include the rtl8366 kernel driver. Signed-off-by: Tobias Diedrich <ranma+openwrt@tdiedrich.de>
