This migrates from the old bitrotted kgdb stub implementation and moves
to the generic stub. In the process support for SH-2/SH-2A is also added,
which the old stub never provided.

The INTEVT read at interrupt exception entry is uneccessary, as the read
is deferred until we are ready to enter do_IRQ(). The kgdb nmi path still
requires it, so move it there.
