Running tip of tree qdl runs without error, returning after 1 second; seems fast.

Seems maybe the loader (prog_emmc_firehose_8916.mbn) needs to be updated.

This commit of qdl works: https://git.codelinaro.org/clo/qcomlt/qdl/-/tree/7f75f17c534211ffe5eac93f4e818027368193a7

Bjorn and I had some discussion about 8916 apparently being "special" in the other PR - #31 (comment)

Is there a chance it'd work with just this diff?

I’m in the middle of a move. Will confirm change next week.

@quic-kdybcio Just checked the recommended change. No impact.

Also note the qdl repo (tip of tree) does not work on db410c; I had to roll back quite a few commits to get it to work; https://git.codelinaro.org/clo/qcomlt/qdl/-/tree/7f75f17c534211ffe5eac93f4e818027368193a7
