sunxi: psci: Move entry address setting to separate function
Currently we set the entry address in the psci_cpu_on function.
However R40 has a different register for this. This resulted in
an #ifdef / #else block in psci_cpu_on, which we avoided having
in the first place.
Move this part into a separate function, defined differently for
the R40 as opposed to the other single cluster platforms.
