PCI: imx6: Configure PHY based on Root Complex or Endpoint mode
[ Upstream commit de22e20589b79f35f92543119c33051f8179dba0 ]
Pass PHY_MODE_PCIE_EP if the PCI controller operates in Endpoint (EP) mode,
and fix the Root Complex (RC) mode being hardcoded using a drvdata mode
check.
Fixes: 8026f2d8e8a9 ("PCI: imx6: Call common PHY API to set mode, speed, and submode")
