CPU: Introduce ARCH_HAS_CPU_AUTOPROBE and X86 parts
This patch is based on Andi Kleen's work:
Implement autoprobing/loading of modules serving CPU
specific features (x86cpu autoloading).
And Kay Siever's work to get rid of sysdev cpu structures
and making use of struct device instead.
Before, the cpuid driver had to be loaded to get the x86cpu
autoloading feature. With this patch autoloading works through
the /sys/devices/system/cpu object
