target-arm: Breakout integratorcp and versatilepb cpu init
This commit changes the integratorcp and versatilepb CPU initialization from
using the generic ARM cpu_arm_init function to doing it inline. This is
necessary in order to allow CPU configuration changes to occur between CPU
instance initialization and realization. Specifically, this change is in
preparation for disabling CPU EL3 support.
