[PATCH 18/26] SCORE: Migrate from 'regset_from_core_section' to 'iterate_over_regset_sections'

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

For S+core targets, no longer define the gdbarch method
'regset_from_core_section', but the iterator method instead.

gdb/ChangeLog:

	* score-tdep.c (score7_linux_regset_from_core_section): Remove.
	(score7_linux_iterate_over_regset_sections): New.
	(score_gdbarch_init): Adjust gdbarch initialization.
