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. Signed-off-by: Rafael J.
