Added BusPort to more accurately emulate the bus requests of the 68k
...
The BusPort is created before the CPU and is passed to it. It can
have an offset, limit the address sizes, and break up bus request
beyond a certain number of bytes into multiple requests

Fixed a bug in bit field instruction decode

We were trying to decode the effective address before fetching the
second instruction word for bitfield instructions, which was causing
it to use the wrong word for the offset:width information, which was
preventing the shell from printing to the screen after boot
