[POWERPC] check firmware state before suspending
Currently the kernel blindly halts all the processors and calls the
ibm,suspend-me rtas call. If the firmware is not in the correct
state, we then re-start all the processors and return. It is much
smarter to first check the firmware state, and only if it is waiting,
call the ibm,suspend-me call.
