[PATCH v2 04/27] bootstd: Correct dependencies on CMDLINE

[Simon Glass]

With recent changes in boot/Kconfig it is no-longer possible to disable
CMDLINE. It results in various link errors because some options which
require CMDLINE are enabled regardless of whether it is available.

Add the necessary conditions to fix this.

Note that it would be better to have all commands depend on CMDLINE,
but that is extremely difficult at present, since some functions use
CMD_xxx to enable feature xxx. For example networking and environment
have a number of problems to tease apart.
