Subject: [PATCH v3 0/2] Add retry tuning sequence

Due to failures to find failing region issues seen on some
boards, add retry tuning sequence to make the tuning algorithm
more robust. The tuning algorithm will re-execute up to 10
times if there is no failing or passing itapdly.

Due to the same issue above, add prints to the tuning algorithm
to make debugging these corner-cases easier.

Changes since v2:
- Use do while loop instead of while in patch 1/2
- Move initialization of tuning_loop to sdhci_am654_init
- Separate error path in patch 1/2
- Move struct *dev = mmc_dev() to patch 2/2
