Some boards need to set the OUTn_MONO register to configurates
the output signal path as a mono differential output. This
wlf,out-mono property is optional. If present, values must be
specified less than or equal to the number of output signals.
If values less than the number of output signals, elements
that has not been specified are set to 0 by default.
Example:
- wlf,out-mono = <1 0 1>; /* set OUT1,OUT3 to mono differential */
