NIOS2: Migrate from 'regset_from_core_section' to 'iterate_over_regset_sections' 

For Nios II GNU/Linux targets, no longer define the gdbarch method
'regset_from_core_section', but the iterator method instead.

gdb/ChangeLog:

	* nios2-linux-tdep.c (NIOS2_GREGS_SIZE): New macro.
	(nios2_regset_from_core_section): Remove.
	(nios2_iterate_over_regset_sections): New.
	(nios2_linux_init_abi): Adjust gdbarch initialization.
