iio: freq: admv1014: Fix warning about dubious x & !y and improve readability
The warning comes from __BF_FIELD_CHECK()
specifically
BUILD_BUG_ON_MSG(__builtin_constant_p(_val) ? \
~((_mask) >> __bf_shf(_mask)) & (_val) : 0, \
_pfx "value too large for the field"); \
The code was using !(enum value) which is not particularly easy to follow
so replace that with explicit matching and use of ? 0 : 1; or ? 1 : 0;
to improve readability.
