PCI: dwc: Call devm_pci_alloc_host_bridge() early in dw_pcie_host_init()

Move devm_pci_alloc_host_bridge() to the beginning of dw_pcie_host_init().

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

[bhelgaas: reorder earlier in series]
