Newer cores in upcoming platforms may refuse to power down. The PSCI library is already prepared for this so convert platform code to also allow this. This is simple - drop the `wfi` + panic and let common code deal with the fallout. The end result will be the same (sans the message) except the platform will have fewer responsibilities. The only exception is for cores being signalled to power off gracefully ahead of system reset. That path must also be terminal so replace the end with the same psci_pwrdown_cpu_end() to behave the same as the generic implementation. It will handle wakeups and panic, hoping that the system gets reset from under it. The dmb is upgraded to a dsb so no functional change.
