This reverts commit 8bc3542384e3a1219e5ffb62b79d16dddc1b1fb9, reversing
changes made to 698edd63eca090a2e299cd3facf90a0b97bed677.

There are still problems with this series to work out.

Any 'bootable' flag in a DOS partition causes boostd to only scan
bootable partitions for that media. This can mean that extlinux.conf
files on the root disk are missed.

Put this logic behind a flag and update the documentation.

For now, the flag is enabled, to preserve the existing behaviour of
bootstd which is to ignore non-bootable partitions so long as there is
at least one bootable partition on the disk.  Future work may provide a
command (or some other mechanism) to control this.

This value is include the bootm_info, so drop the unnecessary parameter.

The address of the bzImage is not recorded in the bootflow, so we cannot
actually locate the version at present. Handle this case, to avoid
showing invalid data.

Rather than holding the state in the implementation code, move it to the
command code. The state is now passed to the implementation functions
and can there (with future work) be pass in from bootstd, without going
through the commands.

Use an alist for this data structure as it is somewhat simpler to
manage. This means that bootstd holds a simple list of bootflow structs
and can drop it at will, without chasing down lists.

This relates to more than just the bootdev, since there is a global list
of bootflows. Move the function to the bootstd file and rename it.

When the buffer address is not set, say so, rather than showing an
address which looks very strange, on sandbox.

This should really use an address rather than the buffer. Update it in
the command.
