PCI: imx6: Add runtime PM support for i.MX95

Browse source

Enable runtime PM support for i.MX95 PCIe Root Complex to allow dynamic
power management when the PCIe link is idle.

The i.MX95 PCIe controller supports entering D3hot state when PCIe
devices are not actively in use. This implementation uses
pm_runtime_no_callbacks() to leverage the PCI core's generic runtime PM
handling. The PCI core automatically manages D-state transitions based
on the runtime PM state of connected endpoint devices.
