[PATCH 1/5] devinfo: use subtree only with devinfo

[Robert Schwebel]

The do_devinfo_subtree() function is only used if devinfo is compiled
in, so put it under the same ifdef. This avoids the following warning
when built with allnoconfig:

lib/driver.c:247: warning: 'do_devinfo_subtree' defined but not used

[PATCH 4/5] allno: make simple shell the default

[Robert Schwebel]

Reorder the shells in Kconfig, in order to make the simple shell the
default over hush. For the sandbox_defconfig this makes the image
smaller:

The simple shell is mostly unused in barebox and most boards depend on
hush in their default environment. It shouldn't be made default.

I would expect 'make allnoconfig' to make a minimum image, but it
currently builds in hush. Any idea how to solve this?
