cb5cbfd503 dm: cpu: Test against cpu_ops->get_info in cpu_get_info()
In cpu_get_info() it wrongly tests against cpu_ops->get_desc to see
if it is NULL. It should test against cpu_ops->get_info.

11f4dc1583 dm: Implement a CPU uclass
It is useful to be able to keep track of the available CPUs in a multi-CPU
system. This uclass is mostly intended for use with SMP systems.

The uclass provides methods for getting basic information about each CPU.
