PCI: dwc: Add PCI ID for LECARC PCIe PMU

Browse Source 
Add support for the PCIe PMU found on LECARC SoCs.

LECARC platforms use the standard DesignWare PCIe Controller, and the
existing DWC driver already handles the enumeration and basic
functionality through the generic PCIe core.

Hence, add the PCI vendor ID to the vendor-specific capability (VSEC) list,
which enables the standard DWC RAS/DES feature detection.
