Don't populate const array ch_to_mux on the stack, instead
make it static. Makes the object code smaller by over 200 bytes:
Before:
text data bss dec hex filename

After
text data bss dec hex filename
12353 1744 128 14225 3791 drivers/iio/adc/ti-adc12138.o
(gcc version 7.2.0 x86_64)

The equivalent of both of these are now done via macro magic when
the relevant register calls are made. The actual structure
elements will shortly go away.

This adds Texas Instruments' ADC12130/ADC12132/ADC12138 12-bit plus
sign ADC driver. I have tested with the ADC12138. The ADC12130 and
ADC12132 are not tested but these are similar to ADC12138 except that
the mode programming instruction is a bit different.
