Merge patch series "bootstd: rauc: fix doc and info msg to reflect real flow"

Andreas Pretzsch <apr@cn-eng.de> says:

For the RAUC bootmethod, newly introduced in U-Boot 2025.10, both code
and documentation contain some incorrect (maybe outdated) statements,
so they do not reflect the real behaviour.
This series corrects both the docs and one log_info in the code, to now
reflect the real flow. Beside being visible in the code, all of it was
tested on a real machine.

Despite the very late time in RC cycle, I suggest inclusion before release
of U-Boot 2025.10, as the current statements are simply incorrect. Also I
do not see any risk in these non-functional changes.
Thanks to Martin Schwan for the review and esp. the initial code!
