c9e5af30fa Disable PMP checker to fix test loops
There is a bug in the PMP checker where S or U mode attempts to make a
memory access while no PMP registers are set. We currently treat this as
a failure, when this should instead be allowed.

7f38056879 fixed subtle typo in icache fsm. Was messing up hit spill hit.
I believe the mibench qsort benchmark runs after this icache fix.

a54c231489 Eliminated extra register and fixed ports to icache.
Still need to support physical tag check and write in icache memory.
Still need to reduce to 1 port SRAM in icache.
I would like to refactor the icache code.
