Parameter and pinout cleanup: take2
Hi Arjan. This is directly related to #277. I believe it addresses all you issues in that pull-request, plus a few other items I've been meaning to clean up. It also updates the CV32E40P_HASH and FPNEW_HASH variables to point to the latest RTL (which Davide has indicated is good ready for verif to use).
If you approve this PR I will kill #277.
