dm_test: improve the appearance shown by "dm tree" command
The command "dm tree" lists devices in a tree-like format. This commit makes it look more like what the Unix command "tree" shows. => dm tree Class Probed Name ---------------------------------------- root [ + ] root_driver demo [ ] |-- demo_shape_drv demo [ ] |-- demo_simple_drv demo [ ] |-- demo_shape_drv demo [ ] |-- demo_simple_drv demo [ ] |-- demo_shape_drv test [ ] |-- test_drv test [ ] |-- test_drv test [ ] |-- test_drv gpio [ ] |-- gpio_sandbox serial [ ] |-- serial_sandbox serial [ + ] |-- serial demo [ ] |-- triangle demo [ ] |-- square demo [ ] |-- hexagon gpio [ ] |-- gpios spi [ ] |-- spi@0 spi_emul [ ] | `-- flash@0 cros_ec [ + ] `-- cros-ec@0 Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
