[Patch,AVR]: Fix missing prototype warning for ACCUMULATE_OUTGOING_ARGS

[Georg-Johann Lay]

Some parts outside the backend use ACCUMULATE_OUTGOING_ARGS without including
tm_p.h which lead to a build warning because avr.h does

#define ACCUMULATE_OUTGOING_ARGS avr_accumulate_outgoing_args()

This patcs moved the prototype from avr-protos.h to avr.h:

        * config/avr/avr-protos.h (avr_accumulate_outgoing_args): Move
        prototype from here to...
        * config/avr/avr.h: ...here.

Ok for trunk?

Johann
