It seems that I should change architecture codes if I need other interfaces.
Under this implementation, I should add my own interface to generic codes,
such as, arch/arm/include/asm/kvm_psci.h. However, I think that it is not
acceptable to upstream. If so, is there any place to define a platform
specific PSCI functions?
