Subject: [PATCH v12 08/13] PCI: dwc: ep: Call epc_create() early in dw_pcie_ep_init()

From: Bjorn Helgaas <bhelgaas@...gle.com>

Move devm_pci_epc_create() to the beginning of dw_pcie_ep_init().

devm_pci_epc_create() is generic code that doesn't depend on any DWC
resource, so moving it earlier keeps all the subsequent devicetree-related
code together.
