When we have multi cpu support compiled in we need the cpu architecture
early so that we can pick the correct cacheflush function. Make it available
as static inline function and add a comment above it that this function
normally should not be used.

Once we run on multiple SoCs we must know which arm architecture we
are on. Add cpu_architecture() from the kernel to detect it.
