The platform id is used to determine the spi bus number, so it should better be different to the ids used for imx51-ecspi. Otherwise it's not possible to use both devices "imx51-cspi.0" and "imx51-ecspi.0". Alternative approaches are to use dynamic bus numbering as offered by the spi framework or let the machine code set the bus number. The downside of both possibilities is that the bus number isn't fixed for the same busses on different machines using i.MX51.
