Use gdbarch for most target parameters for the MN10300, rather

than the tm-*.h file.

Delete definitions.  We register gdbarch methods for these now.
(struct frame_info, struct type, struct value): Delete forward
declarations of these types; they're no longer necessary, since we
don't have function declarations here any more.
* mn10300-tdep.c: #include "arch-utils.h", to get declarations for
some default gdbarch methods.
(mn10300_store_struct_return): Return void, as expected by
gdbarch.
(mn10300_init_extra_frame_info): Take initial `fromleaf' argument,
as expected by gdbarch.
(mn10300_frame_init_saved_regs): Provide dummy definition for
this, as required by gdbarch.
(mn10300_gdbarch_init): Add mn10300_call_dummy_words, as expected
by gdbarch.  Register gdbarch methods or values for all the stuff
removed from tm-10300.h, listed above.
