Make use of the default gdbarch method gdbarch_unwind_pc 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:
* sparc-tdep.c (sparc_unwind_pc): Delete.
(sparc32_gdbarch_init): Don't register deleted function with
gdbarch.
