Resizable BAR driver selects max available BAR size to configure for use. It may happen that some PCIe device declare support for size that exceeds processor address width. Platform needs a way to define the max size it can accept. This change introduce PCD called PcdPcieResizableBarMaxSize. It is dynamic PCD where platform can provide its limit for BAR size. Such PCD can be also controlled with a configuration knob. Signed-off-by: Jacek Kolakowski <Jacek.Kolakowski@intel.com> (cherry picked from commit 24eddc6)
