Create a dedicated I/O core for System 2x6

[Hydreigon223]

Let's face it. It's getting to the point where hardwiring a ps2 controller to the JVS (or sub board) logic won't cut it. Aside from the fact the ps2 controller ports are rarely used with s2x6, a dedicated I/O core would not only allow binding inputs easier but open up a lot of options for other I/O besides JVS. Examples include:

• Racing games no longer require mapping pedals in a weird way due to it originally mapped to an analog stick instead of trigger.
• Add missing JVS inputs (e.g. coinage)
• Sys246 jamma board used in most fighting games.
• Secondary serial port for games that utilize this (e.g. the STR feedback board).
• Tertiary serial port within the JVS I/O. Most touchscreens and Battle Gear 3 use this feature with the latter required to communicate with its feedback board.
• Card readers

I wonder if basing some work on how OpenJVS implements stuff could help... taking into account the fact that a lot of the "most wanted" inputs are already "working".

I'm all out for this, +1.
