dt-bindings: PCI: snps,dw-pcie-ep: Add vendor specific reg-name

Considering that some drivers (e.g. pcie-dw-rockchip.c) already use the
reg-name "apb" for the device tree binding in Root Complex mode
(snps,dw-pcie.yaml), it doesn't make sense that those drivers should use a
different reg-name when running in Endpoint mode (snps,dw-pcie-ep.yaml).

Therefore, since "apb" is already defined in snps,dw-pcie.yaml, add it
also for snps,dw-pcie-ep.yaml.
