[PATCH 19/25] gdb/tic6x: Use default gdbarch methods where possible

[Andrew Burgess <andrew dot burgess at embecosm dot com>]

Make use of the default gdbarch methods for gdbarch_dummy_id, and
gdbarch_unwind_sp where possible.

I have not tested this change but, by inspecting the code, I believe
the default methods are equivalent to the code being deleted.

gdb/ChangeLog:

	* tic6x-tdep.c (tic6x_unwind_sp): Delete.
	(tic6x_dummy_id): Delete.
	(tic6x_gdbarch_init): Don't register deleted functions with
	gdbarch.
