Some boards need to set the INn_MODE[1:0] register to change
the input signal patch. This wlf,inmode property is optional.
If present values must be specified by the number of
ARIZONA_MAX_INPUT.

Example:
   - wlf,inmode = <2 0 2 0>;	/* IN1, IN3 use DMIC */

Might be better to allow the device tree to be shorter than the
array in pdata, should this get expanded on future devices.

OK, I will fix in v2 to use "of_property_count_u32_elems" and "of_property_read_u32_index".
