regmap: Don't generate gather writes for single register raw writes Since it is quite common for single register raw or async writes to be generated by rbtree cache syncs or firmware downloads and essentially all hardware will be faster with only a single transfer optimise this case by copying single values into the internal scratch buffer before sending.
