[Coco] Disto 4-in-1 clock2 with CocoSDC

[Bob Devries]

Hi Chris,

I have opted to change the single entry in clock2_disto4.asm from 
MPI.Slot-1 to MPI.Slot.

My reason is that I have no idea if the entry in coco.d is used by other 
files, whilst I know that the change in clock2_disto4.asm is the only 
place where I'm changing it.
