This fixes 2 bugs:
1. the AGP calculation wasn't consistent with the PCI(E) calc for the
RPTR_ADDR registers. This consolidates the writes and fixes it up.

2. The scratch address was being incorrectly calculated, this breaks
it out into a lot more linear steps.

a lot of perspectives but look like r600s from a memory controller
point of view.
