cpuid: Add helper function for cpuid(1) functions
This patch introduces 3 helper function for cpuid(1) : 1. cpu_get_cpuid() -> to get processor id (from cpuid.eax) 2. cpu_get_feature_flags_ecx -> to get processor feature flag (from cpuid.ecx) 3. cpu_get_feature_flags_edx -> to get processor feature flag (from cpuid.edx) Above 3 helper functions are targeted to replace majority of cpuid(1) references.
