QC suggestions for RC1 (some minor clarifications) #71

Removal of "allow/disallow" only option from Smmtt34
adding explicit statement how many SDs are supported by SmMTT
clarification that permission attribute is "disallowed" not allowed
ambiguity: "MTT structure accesses" -> MTT checker accesses to MTT structures
clarification to informative statement on MTT lookups in section 4.4: Chapter 2 states that when Smmtt is implemented, MTT and e(PMP) are always active. Hence the phrases "while active / no longer active" can be misleading.
