ARM: Migrate from 'regset_from_core_section' to 'iterate_over_regset_sections'

For ARM BSD targets, don't define the gdbarch method
'regset_from_core_section', but the iterator method instead.

gdb/ChangeLog:

	* arm-tdep.h (armbsd_regset_from_core_section): Remove prototype.
	(armbsd_iterate_over_regset_sections): New prototype.
	* armbsd-tdep.c (armbsd_regset_from_core_section): Remove.
	(armbsd_iterate_over_regset_sections): New.
	* armobsd-tdep.c (armobsd_init_abi): Adjust gdbarch
	initialization.
