target-arm: Stop underdecoding ARM946 PRBS registers
The ARM946 has 8 PRBS (protection region base and size) registers. Currently we implement these with a CP_ANY reginfo; however this underdecodes (since there are 16 possible values of CRm but only 8 registers) and we catch the invalid values in the read and write functions. However this causes issues with migration since we only migrate the first of a wildcard register set, so we only migrate c6_region[0]. It also makes it awkward to pull reginfo access checks out into their own function. Avoid all these problems by just defining separate reginfo structs for each of the 8 registers; this also lets us avoid having any read or write functions and will result in more efficient direct field accesses from generated code.
