fdt: Fix uncompress_blob() for U-Boot proper
When U-Boot proper is compiled with CONFIG_MULTI_DTB_FIT and tries
to call uncompress_blob(), it fails with -ENOTSUPP. This is because
the full implementation of this function which includes compression
is available only in SPL. In U-Boot proper or if the compression is
not enabled, the blob is not compressed and thus can be passed to
locate_dtb_in_fit() in fdtdec_setup() without any changes. Pass the
blob without any changes if compression is not enabled instead of
failing.

dm: core: Widen the dump tree to show more of the driver's name.
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.
