ARM / Samsung: Use struct syscore_ops for "core" power management
Replace sysdev classes and struct sys_device objects used for "core"
power management by Samsung platforms with struct syscore_ops objects
that are simpler.
This generally reduces the code size and the kernel memory footprint.
It also is necessary for removing sysdevs entirely from the kernel in
the future.
