gdb/iq2000: Use default gdbarch methods where possible

Browse Source 
Make use of the default gdbarch methods for gdbarch_dummy_id,
gdbarch_unwind_pc, 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:

	* gdb/iq2000-tdep.c (iq2000_unwind_sp): Delete.
	(iq2000_unwind_pc): Delete.
	(iq2000_dummy_id): Delete.
	(iq2000_gdbarch_init): Don't register deleted functions with
	gdbarch.
