Actually we don't have free gpio's in evb boards to use as chip select for ssp.
So didn't add any spi devices here in this array. It is just added here so that
anybody who needs to test it can simply come here, add a device and test.
Can we keep it as it is?

will be done. BUG_ON() can be added here.
