m6801: Attempt at cleaning up internal registers (nw)
- Split "HD6301" and "HD63701" devices into several different types (functionally identical now, but won't be compatible once accuracy improves) - Split the all-in-one m6801_io_r and m6801_io_w handlers into separate handlers for each register; use m() instead of rw() to map these for now - Make all port direction registers write-only - Delete the "unused" NOP mapping from $0020 to $007F in the MC6803 internal map (datasheets make clear that external accesses can be made here) mc10.cpp: Remove a bizarre and seemingly useless DDR hack for an unused port (nw) psion.cpp: Correct CPU types and clocks
