The ARM946 model currently uses the c5_data and c5_insn fields in the CPU state struct to store the contents of its access permission registers. This is confusing and a good source of bugs because for all the MMU-based CPUs those fields are fault status and fault address registers, which behave completely differently; they just happen to use the same cpreg encoding. Split them out to use their own fields instead. These registers are only present in PMSAv5 MPU systems (of which the ARM946 is our only current example); PMSAv6 and PMSAv7 (which we have no implementations of) handle access permissions differently. We name the new state fields accordingly. Note that this change fixes a bug where a data abort or prefetch abort on the ARM946 would accidentally corrupt the access permission registers because the interrupt handling code assumed the c5_data and c5_insn fields were always fault status registers.
