External Local Bus Interface (ELBI) is an optional register space for all DWC IPs containing the vendor specific registers. There is no need for the vendor glue drivers to fetch and map the ELBI region separately. Hence, optionally fetch and map the resource from DT in the DWC core. This also warrants dropping the corresponding code from glue drivers. Hence, drop the ELBI resource fetch and map logic from glue drivers and convert them to use 'dw_pci::elbi_base'. Note that the pcie-qcom-ep driver used devm_pci_remap_cfg_resource() to map the ELBI resource previously. But it was a mistake since devm_pci_remap_cfg_resource() should only be used for mapping the PCIe config space region as it maps the region as Non-Posted. As ELBI is used to hold vendor specific registers, there is no need to map the region as Non-Posted. With this conversion, the region will get mapped as normal MMIO memory.
