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