Re: [PATCH 02/33] drivers: base: cacheinfo: Add helper to find the cache size from cpu+level

MPAM needs to know the size of a cache associated with a particular CPU.
The DT/ACPI agnostic way of doing this is to ask cacheinfo.

Add a helper to do this.

Changes since v1:

You marked this as v1.

 * Converted to kdoc.
 * Simplified helper to use get_cpu_cacheinfo_level().

Please use consistent subject prefixes. Look at previous patch subject
