iio: adc: mcp320x: support more differential voltage measurement
mcp320x driver supports the pseudo-differential mode by
in_voltage'IN+'-voltage'IN-'_raw where (IN+, IN-) = (0, 1), (2, 3), ...
mcp320x chips except MCP3X01 can also select swapped IN+ and IN-
pairs in the pseudo-differential mode.
i.e. in_voltage'IN+'-voltage'IN-'_raw where (IN+, IN-) = (1, 0),
(3, 2), ...
If the voltage level of IN+ is equal to or less than IN-, the
resultant code will be 000h. So it is useful to provide these, too.
