740d5d34b1 cpu: Add support for microcode version and CPU ID
Some CPUs use microcode and each core can have a different version of
microcode loaded. Also some CPUs support the concept of an integer ID used
for identification purposes. Add support for these in the CPU uclass.

11f4dc1583 dm: Implement a CPU uclass

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