[PATCH v3 2/5] mfd: arizona: Update DT bindings to add CS47L24 and WM1831

[Richard Fitzgerald <rf@opensource.wolfsonmicro.com>]

This updates the Arizona MFD device tree bindings to add the
Cirrus Logic CS47L24 and WM1831 codecs. Note that unlike all the
other codecs the DCVDD-supply and MICVDD-supply are mandatory.
