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.

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.
