hng64: allow IOMCU to trigger MIPS IRQs (#3838)

Browse Source 
* allow IOMCU to trigger MIPS IRQs

allows coinage hack in Buriki to go away
allows roadedge to be coined up / go into test mode (game still broken)
properly mapped inputs for roadedge / xrally

xrally coin sound plays, but game doesn't seem to coin up or start (probably knows something else is wrong)

currently only the magic 'machine code' faked via the MCU sim, everything else is going through the MCU.

* unused ports are active low (nw)

* these no longer needed (nw)
