Add PCI_VENDOR_ID_ROCKCHIP to the list of RAS DES vendor specific ids.
Tested using the RAS DES DWC debugfs changes that was merged recently.
drivers/perf/dwc_pcie_pmu.c driver has not been tested, but considering
RAS DES works in DWC debugfs, I see no reason why RAS DES shouldn't work
in drivers/perf/dwc_pcie_pmu.c.

Note: this depends on DWC debugfs patches that are queued up in branch
controller/dwc and the PCI_VENDOR_ID_ROCKCHIP patch on branch
controller/rockchip.

Applied to controller/dwc, thank you!
