gdb/m68hc11: Use default gdbarch methods where possible
Make use of the default gdbarch methods for 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: * m68hc11-tdep.c (m68hc11_unwind_pc): Delete. (m68hc11_unwind_sp): Delete. (m68hc11_gdbarch_init): Don't register deleted functions with gdbarch.
