PM / UNICORE32: Use struct syscore_ops instead of sysdevs for PM 



Make some UNICORE32 architecture's code use struct syscore_ops
objects for power management instead of sysdev classes and sysdevs.

This simplifies the code and reduces the kernel's memory footprint.
It also is necessary for removing sysdevs from the kernel entirely in
the future.
