[PATCH v3 45/46] pxe_utils: Refactor to separate reading from booting

[Simon Glass]

It is useful to be able to select a bootflow and read its images,
without actually doing the boot. This allows adjusting the bootargs, for
example.

Provide support for this in the pxe_utils module, by adding a 'probe'
method which selects a label and saves its settings, so it can be booted
later, if desired.
