* mn10300-tdep.h (AM33_MODE): Add gdbarch as parameter.

	* mn10300-tdep.c (set_reg_offsets, mn10300_analyze_prologue): Use
	get_frame_arch to get at the current_architecture. Update AM33_MODE
	call.
	(mn10300_analyze_prologue): Add gdbarch as parameter. Update caller.
	(mn10300_frame_unwind_cache): Use get_frame_arch to get at the current
	architecture.
	(set_reg_offsets, mn10300_analyze_prologue): Fix indentation.
