at24 is not a vendor prefix. Either this is atmel specific and you want 
atmel,no-read-rollover or it is for all vendors at24 compatible eeproms 
and you want at24-no-read-rollover. Or just drop the at24 if this 
binding is in fact for just at24 eeproms as none of the other properties 
has at24 in them.
