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 */

of_property_read_u32_array with proplen as the length should be ok here since we know the size is smaller than the inmode array.
