[PATCH v2 2/8] ASoC: arizona: add defines for single-input gain control

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

Adds convenience defines for declaring a gain control that
has an input mux. These blocks are functionally equivalent to
the existing mixer blocks but can only have a single input
active at once.
