h8300-protos.h: Remove the prototype for o_operand. 

	* config/h8300/h8300-protos.h: Remove the prototype for
	o_operand.
	Add prototypes for single_one_operand and single_zero_operand.
	* config/h8300/h8300.c (o_operand): Remove.
	(single_one_operand): New.
	(single_zero_operand): Likewise.
	(print_operand): For 'V' operand, and the operand with 0xff.
	For 'V' and 'W' operands, do not and the bit position with 7.
	* config/h8300/h8300.md (various anonymous patterns): Replace
	use of exact_log2 with single_one_operand/single_zero_operand.
