minmax: reduce min/max macro expansion in atomisp driver

Avoid unnecessary nested min()/max() which results in egregious macro
expansion.

Use clamp_t() as this introduces the least possible expansion, and turn
the {s,u}DIGIT_FITTING() macros into inline functions to avoid the
nested expansion.

This resolves an issue with slackware 15.0 32-bit compilation as
reported by Richard Narron.

Presumably the min/max fixups would be difficult to backport, this patch
should be easier and fix's Richard's problem in 5.15.
