pci: controller: pci-dra7xx: add support for x2 mode On AM57xx, operating PCIE1 in dual-lane mode requires configuring the PCIESS1 controller to manage both the PCIE1 and PCIE2 PHYs. This commit facilitates setting CTRL_CORE_PCIE_CONTROL[2] and CTRL_CORE_PCIE_CONTROL[0], based on dts information, to place PCIESS1 into an x2 mode. PCIESS2 is unusable in this mode. default behavior: PCIESS1 in x1 mode, PCIESS2 in x1 mode. Signed-off-by: Russell Robinson <rrobinson@phytec.com>
