software_isp: Log input config from configure()

As shown by commit 94d32fdc55 ("pipeline: simple: Consider output sizes
when choosing pipe config"), the extra pixel columns CPU debayering
requires on the input side makes resolution selection non trivial.

Add logging of the selected input config on a successful configure() so
that the logs clearly show which sensor mode has been selected.
