Allow disabling PSCI support (mostly for testing purposes) by setting
the status property to "disabled". This makes the node behave in much
the same way as proper device nodes.

This looks sensible to me; FWIW:
Acked-by: Mark Rutland <mark.rutland@arm.com>
Lorenzo, do we need to batch this up with other PSCI patches, or should
this go direct to arm-soc?
Thanks,
Mark.

I am aiming at getting the PSCI checker merged too so that we can send
both patches (and others that may turn up) in one go to arm-soc, I will
handle it.
Thanks !
