TILEGX: Migrate from 'regset_from_core_section' to 'iterate_over_regset_sections'

For TILE-Gx GNU/Linux targets, no longer define the gdbarch method
'regset_from_core_section', but the iterator method instead.

gdb/ChangeLog:

	* tilegx-linux-tdep.c (TILEGX_LINUX_SIZEOF_GREGSET): New macro.
	(tilegx_regset_from_core_section): Remove.
	(tilegx_iterate_over_regset_sections): New.
	(tilegx_linux_init_abi): Adjust gdbarch initialization.
