PR target/29932
	* config/avr/predicates.md (io_address_operand): Delete predicate.
	(low_io_address_operand): Don't use 'mode' argument.
	(higth_io_address_operand): Rename ...
	(high_io_address_operand): ... to this. Don't use 'mode' argument.
	* config/avr/avr.md (*sbix_branch_tmp, *sbix_branch_tmp_bit7): Adjust
	for above change.
