These scm calls are never used outside of legacy ARMv7 based platforms.
That's because PSCI, mandated on arm64, implements them for modern SoCs
via the PSCI spec. Let's move them to the legacy file and only compile

These scm calls are never used outside of legacy ARMv7 based platforms.
That's because PSCI, mandated on arm64, implements them for modern SoCs
via the PSCI spec. Let's move them to the legacy file and only compile
the legacy file into the kernel when CONFIG_ARM=y. Otherwise provide
stubs and fail
