Overhauled the SiS 496/497 chipset emulation (and added the DRB locking to it) (later Zida Tomato 4DPS BIOS'es now work, and we now use the actual 1.72), fixed the W83787F and FDC37C932FR Super I/O chips, removed the no longer needed Acer M3A registers (that's now correctly handled as FDC37C932FR GPIO), and a number of bugfixes here and there.
