sandbox: Add a -T flag to use the test device tree
U-Boot already supports using -D to indicate that it should use the normal device tree. It is sometimes useful to run with the test device tree, e.g. when running a test. Add a -T option for this along with some documentation. It can be used like this: /tmp/b/sandbox/u-boot -T -c "ut dm pci_busdev" (this will use /tmp/b/sandbox/arch/sandbox/dts/test.dtb as the DT) Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com> Tested-by: Bin Meng <bmeng.cn@gmail.com>
