avr: replace sentinal with iteration from 0 to ARRAY_SIZE
This seems a little easier to understand than using a sentinal, and will
hopefully let the compiler optimize the loop better. It also has the effect
that we stop initializing a field of the sentinal that is an enum with zero.

* config/tc-avr.c (avr_parse_cons_expression): Replace iteration to
sentinal with iteration to array size.
