gdb/arm: Use default gdbarch methods where possible
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/arm-tdep.c (arm_dummy_id): Delete. (arm_unwind_pc): Delete. (arm_unwind_sp): Delete. (arm_gdbarch_init): Don't register deleted functions with gdbarch.
