[PATCH v7 01/10] PCI: imx6: Fix establish link failure in EP mode for iMX8MM and iMX8MP

[Frank Li]

From: Richard Zhu <hongxing.zhu@xxxxxxx>

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: 0c9651c21f2a ("PCI: imx6: Simplify reset handling by using *_FLAG_HAS_*_RESET")
