- Get rid of static_cpu_has() - one less API to care about testing CPU
  features

- Unify the handling of CPU core types (performance, efficient, etc) by
  mapping the vendor-specific types to Linux ones

- Continuation of the work of Ahmed Darwish to centralize CPUID leafs
  representation

x86/CPU: Rename struct cpuid_read_output to struct cpuid_output

There's no CPUID "write" operation so there's no need to have
a cpuid_read_output thing - cpuid_output is perfectly clear. And
shortens the code just fine.

Remove the funky function signature line breaks while at it.

No functional changes.
