dt-bindings: PCI: designware: Example update 



Replace "ctrlreg" reg-name by "dbi" to be coherent with similar drivers,
however it still be compatible with any previous DT that uses the old
reg-name.

Replace the PCIe base address example by a real PCIe base address in use.

Required properties:

- compatible: should contain "snps,dw-pcie" to identify the core.

- compatible:

	"snps,dw-pcie" for RC mode;

- reg: Should contain the configuration address space.

- reg-names: Must be "config" for the PCIe configuration space.
