iio: dac: adi-axi: fix a mistake in axi_dac_ext_info_set()
The last parameter of these axi_dac_(frequency|scale|phase)_set()
functions is supposed to be true for TONE_2 and false for TONE_1. The
bug is the last call where it passes "private - TONE_2". That
subtraction is going to be zero/false for TONE_2 and and -1/true for
TONE_1. Fix the bug, and re-write it as "private == TONE_2" so it's
more obvious what is happening.
