soc/amd/common/cpu/noncar: Compute core info

In some SoC like Glinda, have
1. Different CPU cores have slightly different max boost frequency,
2. Multiple L3 cache blocks of different size identified by unique ID.

Add helper function,
1. get_max_boost_frequency() to compute max boost frequenncy.
2. ap_stash_core_info() to update core_info struct with max boost
   frequency & all L3 cache block uniq ID & its size.

Glinda SoC has multiple L3 caches, each identified by a unique cache
UID. Each core is associated with a specific L3 cache, which can be
determined based on the CPU core ID.

The default implementation (x86_get_cpu_cache_info) retrieves cache
information only for the current core and assumes that the same L3 cache
is shared across all cores.

To accurately determine the total L3 cache size:
1. Retrieves L3 cache information for each CPU core.
2. Identifies the unique cache ID associated with each core.
3. Aggregates cache sizes for all unique cache IDs to compute the total
   L3 cache size, ensuring correct summation even when L3 cache blocks
   have different sizes.

TEST=Build for Glinda SoC, with L3 cache = 16MB + 8MB. Ran command
'dmidecode -t 7' & verified L3 cache is 24MB.
