Fixes for omaps for v5.12-rc cycle

Fix swapped mmc device order also for omap3 that got changed with the
recent PROBE_PREFER_ASYNCHRONOUS changes. While eventually the aliases
should be board specific, all the mmc device instances are all there in
the SoC, and we do probe them by default so that PM runtime can idle the
devices if left enabled from the bootloader.

Also included are two compiler warning fixes.
