[PATCH v2 1/2] mfd: arizona: Add device tree binding to specify mono outputs

[Charles Keepax <ckeepax@opensource.wolfsonmicro.com>]

Add device tree bindings to support specifying outputs from the chip as
mono outputs. Whilst we are doing it change the out_mono pdata from a
bool to an int, because Sparse gets upset about using ARRAY_SIZE on
bools.

No changes since v1.

Thanks,
Charles
