New skeleton driver: SNES 4 Slot arcade switcher

Browse Source 
Credits: ClawGrip, Roberto Fresca, Recreativas.org,

This is based on an MCS-51 core, like the MK3 bootleg. They are
clearly based on the same code, so the MK3 bootleg was moved to
this driver.

SNES bootlegs controlled by an MCS-51 core
Skeleton driver
Currently there are dumps for a Mortal Kombat 3 board and a board with
4 slots that supports various games directly and also has a generic
timer based mode.
Hardware (for the 4 slot switcher):
- MCS-51 based CPU 44-pin (markings removed)
- WD1016D-PL (?)
- TC5565PL-15 (8k SRAM)
- 12 MHz XTAL
- 4 Position Dipswitch
