dm: Add a new CPU init function which can use driver model
Since driver model is set up after arch_cpu_init(), that function cannot
use drivers. Add a new arch_cpu_init_dm() function which is called
immediately after driver model is ready, and can reference devices.
This can be used to probe essential devices for the CPU.
