Previously, the rocket permissions checker assumed that Rocket could generate Get/Put requests up to CacheBlockBytes in size. This is actually not possible, Rocket by itself will not generate requests > xLen in size.
This relaxes the check within rocket to check for a maxSize of xLen/8.
Implementations which may perform > xLen/8 byte accesses simply set a higher lgMaxSize for the TLB.
