do we really want this CLINT mode xnxti behavior? #374

In CLINT mode, reads of xnxti return 0, updates to xstatus proceed as in CLIC mode, but updates to xintstatus and xcause do not take effect.

In TG discussion, we seemed to think it didn't make sense for xnxti to affect CLINT. will create pull to remove statement allowing updates to xstatus.
