target-arm: cpu64: generalise name of A57 regs

Rename some A57 CP register variables in preparation for support for
Cortex A53. Use "a57_a53" to describe the shareable features. Some of
the CP15 registers (such as ACTLR) are specific to implementation, but
we currently just RAZ them so continue with that as the policy for both
A57 and A53 processors under a shared definition.
