DesignWare MMC Controller's transfer mode should be decided
at runtime instead of compile-time. Add "supports-idmac" for
all platforms that use internal dma mode to enable this feature
at runtime.

I'm wondering if you're going to care about other platforms
that use DW MMC?

Just grep for "snps,dw-mshc", "altr,socfpga-dw-mshc",
"img,pistachio-dw-mshc" and you'll see more dt* files to
be updated.

   Thanks,  Alexey.
   Yes,  I missed some ARC dt*  files just as Vineet told me. It will be 
fixed in v4.
   Btw, I cannot find "img,pistachio-dw-mshc" in 4.2.0-rc3. And no more 
"dw-mshc" or "dwmmc"
   is found.
