[PATCH V3 1/9] uclass: cpu: Add new API to get udevice for current CPU

[PATCH V3 1/9] uclass: cpu: Add new API to get udevice for current CPU

[Peng Fan]

When running on SoC with multiple clusters, the boot CPU may
not be fixed, saying booting from cluster A or cluster B.
Add a API that can return the udevice for current boot CPU.
Cpu driver needs to implement is_current_cpu interface for this
feature, otherwise the API only returns the first udevice in
cpu uclass.
