PS2-HW: Remove address of non-existent registers 

It seems not all DMA channels have the same set of 32 bit registers. Removed
addresses of registers which aren't actually present in the memory
space.

Example: Channel 0/1/2 have address stack registers but the other
channels lack it. According to documents, the remaining memory space of
the channels seems to be reserved. Which means, write access would be
disregarded and read access would return an unknown value.

Credit goes to Gregory and CK1 for notifying me about it, special mention to ssakash for actually pushing the change to github. Also I wasn't the one who introduced the non-existent registers into the code, these registers were present before under a different name.
