[PATCHv1 2/3] arm: mvebu: add .dts file for Synology DS213j

quoted

+				pmx_uart0: pmx-uart0 {
+					marvell,pins = "mpp0", "mpp1";
+					marvell,function = "uart0";
+				};

This however does not seem to be in armada-370.dtsi. This is probably
because there are a few options:

           MPP_FUNCTION(0x0, "gpio", NULL),
           MPP_FUNCTION(0x1, "uart0", "rxd")),
        MPP_MODE(1,
           MPP_FUNCTION(0x0, "gpo", NULL),
           MPP_FUNCTION(0x1, "uart0", "txd")),
        MPP_MODE(2,
           MPP_FUNCTION(0x0, "gpio", NULL),
           MPP_FUNCTION(0x1, "i2c0", "sck"),
           MPP_FUNCTION(0x2, "uart0", "txd")),
        MPP_MODE(3,
           MPP_FUNCTION(0x0, "gpio", NULL),
           MPP_FUNCTION(0x1, "i2c0", "sda"),
           MPP_FUNCTION(0x2, "uart0", "rxd")),

What we found with Kirkwood, is that everybody picks the
same. Probably because of Marvell's RDK and U-boot etc.  It is not
clear from the current 370 boards what is being used. I should go look
at Mirabox and 370 RD. If they are all mpp0 & mpp1, i suggest we put
this into armada-370.dtsi

So i went and checked. Both Mirabox and 370 RD use mpp0 and mmp1. So i
suggest you add these to armada-370.dtsi.
