Replaces "ctrlreg" reg-name by "dbi" to be coherent with similar drivers, however it still be compatible with any previous DT that uses the old reg-name. Replaces the PCIe base address example by a real PCIe base address in use. Signed-off-by: Gustavo Pimentel <gustavo.pimentel@synopsys.com> --- Changes v1->v2: - Removed any iATU reference or changes to avoid confusion. - Add "snps,dw-pcie" compatible string following Kishon's suggestion.
