[PATCH 1/2] arm/mxc: make imx_dma_is_general_purpose more generic for sdma

[Shawn Guo]

The arm-soc maintainers are requiring patch subject be like

ARM: <platform>: ...

In this case, it's "ARM: mxc: ..."

I think this needs some level rewording.  For given SoC, the name is

Other than that, it looks good to me.
