PCI: imx6: Fix establish link failure in EP mode for i.MX8MM and i.MX8MP

Browse Source 
Add IMX6_PCIE_FLAG_HAS_APP_RESET flag to IMX8MM_EP and IMX8MP_EP drvdata.

This flag was overlooked during code restructuring. It is crucial to
release the app-reset from the System Reset Controller before initiating
LTSSM to rectify the issue.

Fixes: 0c9651c21f ("PCI: imx6: Simplify reset handling by using *_FLAG_HAS_*_RESET")
