This series addresses PHY initialization sequence issues for i.MX95 PCIe
that were identified through careful review of the i.MX95 PCIe PHY Databook.

The current implementation does not strictly follow the timing requirements
specified in the PHY documentation for reference clock configuration and
PHY reset sequencing. These violations can potentially lead to unreliable
PHY initialization.

Applied, thanks!
