PCI: imx6: Configure PHY based on Root Complex or Endpoint mode 

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: 8026f2d8 ("PCI: imx6: Call common PHY API to set mode, speed, and submode")
