arm: mvebu: theadorable: Add 'pcie' test command
This board specific command tests for the presence of a specified PCIe device (via vendor-ID and device-ID). If the device is not detected, this will get printed. If the device is detected, the board will get resetted so that an easy loop test can be done. The board will reboot until the PCIe device is not detected. Signed-off-by: Stefan Roese <sr@denx.de>
