[U-Boot] [PATCH v2] dm: core: Widen the dump tree to show more of the driver's name.

[sjg at google.com]

With drivers that have prefix names that are quite long (like
'versatile_') it is useful to have a wider column for the driver's
name when dumping the device driver tree.

Also update the tests to take into account the wider output format.
