arch/arm64: Extend cache helper functions

This patch extends the cpu_get_cache_info function, so that
additional information like size of cache lines can be retrieved.

Furthermore, static functions were grouped and moved to the top and
non-static functions to the bottom, in order to provide a better
structure to the file.

Patch was tested against the qemu-sbsa mainboard.
