allwinner: Leave CPU power alone during BL31 setup

Disabling secondary CPUs during boot is unnecessary because the other
CPUs are already in reset, and it saves an entirely insignificant amount
of power. Let's remove this bit of code that was added mostly "because
we can", and along with it remove an unconditional dependency on the CPU
ops functions.
