[PATCH v4 3/4] PCI: imx6: Pass correct sub mode when calling phy_set_mode_ext()

[Frank Li]

Fix hardcoding to Root Complex (RC) mode by adding a drvdata mode check.
Pass PHY_MODE_PCIE_EP if the PCI controller operates in Endpoint (EP) mode.

Fixes: 8026f2d8e8a9 ("PCI: imx6: Call common PHY API to set mode, speed, and submode")
