gm-matthew 3e394d1257 Only access SCSI device at 0xC0xxxxxx if it has been configured to do so 
Fixes some step 1.5 games not working in last update

Matthew Daniels e93c5d710f PowerPC IRQ line deassertion; DMA only fires interrupts when required 
PowerPC no longer clears its own IRQ line; it is now cleared by the IRQ controller when there are no more pending interrupts. Not all games clear DMA interrupts so it was necessary to tweak the 53C810 SCSI controller and the Real3D DMA interface to only fire interrupts if a certain register is correctly set. 53C810 has the documented DIEN (DMA Interrupt Enable) register; Real3D DMA seems to use the low bit of the dmaConfig register.

Also I removed the net IRQ as no games seem to actually use it.

Matthew Daniels 9ffce8b92a Getting rid of most of the includes from Supermodel.h; each file now explicitly includes the header files it needs. 
Making changes to a header file should no longer force the entire project to recompile.
