[PATCH 0/2] coresight: Fix missing AMBA dev_pm_ops and modernize PM ops

[Eric Chan]

This 2-patch series addresses an issue where CoreSight AMBA drivers (TMC,
CATU, and ETM4x) missed setting their dev_pm_ops during earlier ACPI and
platform driver refactorings, and modernizes runtime PM ops definitions
across these drivers to align with Documentation/power/runtime_pm.rst.

- Patch 1 is a bug fix (marked for stable) that sets the missing .pm
  pointer in the AMBA drivers (tmc_driver, catu_driver, and
  etm4x_amba_driver) so runtime PM suspend and resume callbacks are
  properly invoked when probed via AMBA bus.
- Patch 2 modernizes the runtime PM definitions across TMC, CATU, and
  ETM4x to use DEFINE_RUNTIME_DEV_PM_OPS() and pm_ptr(), eliminating
  unnecessary #ifdef CONFIG_PM blocks.

  coresight: Add missing dev_pm_ops to AMBA drivers
  coresight: Switch to DEFINE_RUNTIME_DEV_PM_OPS()
