In ArmPkg/Include/Chipset, several CPU-specific header files reside.
Most of these provide no actual, or very little, use.
ARM1176JZ-S.h is not used at all (and unusable since SVN r18237).
ArmAemV8.h simply includes AArch64.h.
ArmCortexA15.h defines one processor-specific configuration bit and
then includes ArmV7.h.
Delete these include files, and update their sole users to function
without them.
