Clean up lint errors in fpu and muldiv

booth.sv had an actual error where a signal was being assigned to too
many bits. muldiv has a lot of non blocking assignments, so I suppressed
those warnings so the linter output was readable.

Partially working icache.
...
The current issue is a StallF is required to halt the icache from getting an updated PCF. However
if the dmemory is the reason for a stall it is possible for the icache stall to hold the d memory request continuously causing d memory to repeatedly read from memory. This keeps StallF high and
the icache FSM is never allowed to complete.
