[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. Signed-off-by: Paul Mackerras <paulus@samba.org>
