target-arm: Add AArch64 CPTR registers
Adds CPTR_EL2/3 system registers definitions and access function.
Signed-off-by: Greg Bellows <greg.bellows@linaro.org>
[PMM: merge CPTR_EL2 and HCPTR definitions into a single
def using STATE_BOTH;
don't use readfn/writefn to implement RAZ/WI registers;
don't use accessfn for the no-EL2 CPTR_EL2;
fix cpacr_access logic to catch EL2 accesses to CPACR being
trapped to EL3;
use new CP_ACCESS_TRAP_EL[23] rather than setting
exception.target_el directly]
