Create tdep->rl78_psw_type lazily
I build GDB for all targets enabled. When I "set architecture rl78",
GDB crashes,
(gdb) set architecture rl78
Program received signal SIGSEGV, Segmentation fault.

The cause is that we want to access some builtin types in gdbarch init, but
it is not initialized yet. I fix it by creating the type when it is to be
used. We've already done this in sparc, sparc64 and m68k.
