ARM: Implement a stub of CPACR.
...
This register controls access to the coprocessors. This doesn't actually
implement it, it allows writes which don't turn anything off. In other words,
it allows the simulated program to ask for what it already has.

221e0ac523
ARM: Warn about and ignore accesses to DCCISW.
...
This register is supposed to "Clean and invalidate data or unified cache line
