Subject: [PATCH v3 0/3] clocksource: imx-sysctr: support i.MX95

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

Signed-off-by: Peng Fan <peng.fan@....com>

Changes in v3:
- Drop items in patch 1 per Conor's comments
- Link to v2: https://lore.kernel.org/r/20240125-imx-sysctr-v2-0-7332470cd7ae@nxp.com
