x86/cpu: Use common topology code for Intel
Intel CPUs use either topology leaf 0xb/0x1f evaluation or the legacy
SMP/HT evaluation based on CPUID leaf 0x1/0x4.
Move it over to the consolidated topology code and remove the random
topology hacks which are sprinkled into the Intel and the common code.
No functional change intended.
