platform/efi: platform_cpu_info

* This models the CpuInfo into a cross-architecture
  platform_cpu_info
* Originally I was looking at merging this with "arch_cpu_info"
  however that is "overall cpu" while CpuInfo is "indivial core
  information" packed into an array.
* Since every dtb platform will report individual cores in fdt,
  having a common cpu core info struct with at minimum the core
  id makes sense.
* This could likely be refined further to some kind of core info
  packed inside of arch_cpu_info, but this will fix arm,arm64,etc
  for now until someone wants to dive into that.
