added a few very simple arbitrations in the lsuArb that pass regression. cleaned up a few unused signals. Added several comments and concerns to lsuarb so I can remember where my thoughts were at the end of the day.

Split the ReadDataW bus into two parts in preparation for the data cache. On the AHB side it is now HRDATAW and on the CPU to data cache side it is ReadDataW. lsu.sv now handles the connection between the two.
...
Also reorganized the inputs and outputs of lsu and pagetablewalker into connects between CPU, pagetablewalker, and AHB.
Finally add DisableTranslation to TLB as teh pagetablewalker will need to force no translation when active regardless of the state of SATP.
With Kip.
