The system counter(sys_ctr) is a programmable system counter
which provides a shared time base to Cortex A15, A7, A53, A73,
etc. it is intended for use in applications where the counter
is always powered and support multiple, unrelated clocks. The
compare frame inside can be used for timer purpose.
