Thanks for reviewing. Here it could be changed as :
	Should be one of the following string
	      "st,stm32f7-crc"
	      "st,stm32f4-crc"

Also, example may not contain both binding strings, I think. It could be leaved unchanged
as in the previous version. I will make these changes with this way if it is OK.
