[ARM] Orion: PCIe x4/x1 detection support The Discovery Duo (MV78xx0) has two x4 PCIe ports which can either be used in x4 mode or in quad x1 mode. This patch adds an accessor function to the generic plat-orion PCIe handling code to detect in which of the two modes we're running (which is determined by strap pins and/or configured by the bootloader).
