This is like commit 3d3451124f3d ("mmc: sdhci-msm: Prefer asynchronous
probe") but applied to a whole pile of drivers.  This batch converts
the drivers that appeared to be around in the v4.14 timeframe.

The LTS granularity of patches is a nice idea! I will keep it in mind.

In general, I like more coverage of async probing. It makes sense for
SD/MMC, I think.

For these two also:

The speedups somewhat match the expected values and no regressions when
checksumming a large file.
