i.MX95 System Counter module control register space is blocked
by SCMI firmware, so we use Read Register space to get the counter.

V2:
  - imx95 is not compatible with the existing hardware, so add a
    seperate entry for i.MX95 in dt-binding.
  - Per Marco's comments, the global variables was removed except
    to_sysctr. And add a new TIMER_OF_DECLARE entry for i.MX95
