cacheinfo: Move cache_leaves_are_shared out of CONFIG_OF

cache_leaves_are_shared is already used even with ACPI and PPTT. It
checks if the cache leaves are the shared based on fw_token pointer.
However it is defined conditionally only if CONFIG_OF is enabled which
is wrong.

Move the function cache_leaves_are_shared out of CONFIG_OF and keep it
generic. It also handles the case where both OF and ACPI is not defined.
