    arm64: Implement PSCI command support
    
    Provide support for SoCs to participate in PSCI commands.
    There are 2 steps to a command:
    1. prepare() - look at request and adjust state accordingly
    2. commit() - take action on the command
    
    The prepare() function is called with psci locks held while
    the commit() function is called with the locks dropped.
    No SoC implements the appropriate logic yet.
    
    BUG=chrome-os-partner:32136
    BRANCH=None
    TEST=Booted PSCI kernel -- no SMP because cmd_prepare()
         knowingly fails. Spintable kernel still brings up both
         CPUs.
