intel/i440bx: Correct RAM init programming

Corrects MBSC/MBFS programming when initializing DRAM on boards with both
3 and 4 DIMM slots.

Reformats comments to current coreboot standards.

Drops some romcc "optimizations" no longer necessary.

Boot tested on asus/p2b-ls, where it fixes a memory related hang after
SeaBIOS resets the board with nothing to boot from.
