target-arm: Introduce per-CPU field for PSCI version
We require to know the PSCI version available to given CPU at
potentially many places. Currently, we need to know PSCI version
when generating DTB for virt machine.
This patch introduce per-CPU 32bit field representing the PSCI
version available to the CPU. The encoding of this 32bit field
is same as described in PSCI v0.2 spec.
