[PATCH][v2] arm64: Add DTS support for FSL's LS1012A SoC

[Yao Yuan]

Hi Shawn and All,

Any comment for this LS1012A platform support patch?

Is this a good enough base for consequence dts update patches?  

If yes, I'd like to send some dts patches for DSPI and QSPI based on this patch. 

Thanks.
Yao
