PCI: dwc: Add new APIs to remove standard and extended Capability
On some platforms, certain PCIe Capabilities may be present in hardware
but are not fully implemented as defined in PCIe spec. These incomplete
capabilities should be hidden from the PCI framework to prevent unexpected
behavior.
Introduce two APIs to remove a specific PCIe Capability and Extended
Capability by updating the previous capability's next offset field to skip
over the unwanted capability. These APIs allow RC drivers to easily hide
unsupported or partially implemented capabilities from software.
