This patch is used to support DBD owner fuse changed to S400 only. The XRDC PDAC2 for LPAV pbridge5 and MSC1/2/3 for GPIO and LPAV are not configured by S400 default setting. So these PDAC and MSC are invalid, only DBD owner can access the corresponding resources. We have to configure necessary PDAC and MSC for SPL before DDR initialization.
