ARM: dts: imx6: enable Murata 1MW M.2 card for imx6 legacy platforms

Enable Murata 1MW M.2 card for i.MX6 legacy platforms. Plug in
Murata 1MW M.2 into SD slot by using Murata uSD-to-M.2 Adapter.

Below i.MX6 legacy platforms will be supported:
- i.MX6Q/QP/DL SDB, SD2 slot
- i.MX6SX SDB, SD2 slot
- i.MX6SLL EVK, SD3 slot
- i.MX6UL/ULL/ULZ EVK, SD1 slot
