[PATCH 23/26] XTENSA: Migrate from 'regset_from_core_section' to 'iterate_over_regset_sections'

[Andreas Arnez <arnez at linux dot vnet dot ibm dot com>]

For Xtensa targets, no longer define the gdbarch method
'regset_from_core_section', but the iterator method instead.

gdb/ChangeLog:

	* xtensa-tdep.c (xtensa_regset_from_core_section): Remove.
	(xtensa_iterate_over_regset_sections): New.
	(xtensa_gdbarch_init): Adjust gdbarch initialization.
