arch/x86: Helper functions to get deterministic cache parameters

This patch creates helper function that internally detects the CPU
type (AMD or Intel) and pick the leaf to send CPUID instruction with
different cache level to retrieve deterministic cache parameters.

Lists of helper functions generated as part of this CL :
1. cpu_check_deterministic_cache_cpuid_supported => if CPU has support
for deterministic cache using CPUID instruction.
2. cpu_get_cache_ways_assoc_info => Get cache ways for associativity.
3. cpu_get_cache_type => Get cache type.
4. cpu_get_cache_level => Get cache level.
5. cpu_get_cache_phy_partition_info => Get cache physical partitions.
6. cpu_get_cache_line_size => Get cahce line size.
7. cpu_get_cache_sets => Get cache number of sets.
8. cpu_is_cache_full_assoc => Check if cache is fully associative.
9. cpu_get_max_cache_share => Cores are sharing this cache.
10. get_cache_size => Calculate the cache size.
