Liav A 75f01692b4 Kernel+Userland: Move /sys/firmware/power_state to /sys/kernel directory
Let's put the power_state global node into the /sys/kernel directory,
because that directory represents all global nodes and variables being
related to the Kernel. It's also a mutable node, that is more acceptable
being in the mentioned directory due to the fact that all other files in
the /sys/firmware directory are just firmware blobs and are not mutable
at all.
