gdbarch software_single_step frame_info to regcache: nios2

gdb:

2016-11-22  Yao Qi  <yao.qi@linaro.org>

	* nios2-tdep.c (nios2_get_next_pc): Replace parameter frame
	with regcache.  Call regcache_raw_get_signed instead of
	get_frame_register_unsigned.
	(nios2_software_single_step): Call get_regcache_arch
	instead of get_frame_arch.
