soc/intel/meteorlake: Implement report_cache_info() function
Make use of deterministic cache helper functions from Meteor Lake
SoC code to print useful information during boot as below:
Cache: Level 3: Associativity = 12 Partitions = 1 Line Size = 64
Sets = 32768
Cache size = 24 MiB
Port of commit 55f5410fcd78 ("soc/intel/alderlake: Implement report_cache_info() function")
BUG=none
