I think we shouldn't consider there to be an SDHCI order problem.
Relying on block devices to appear with a specific name is probably
something we shouldn't do. The fact it happened with SDHCI is pretty
unique; it doesn't for USB-attached devices, removable SDHCI devices, etc.

Instead, you can use partition or filesystem UUIDs to name devices. I
boot with root=PARTUUID=xxxx these days, and hence never have to adjust
my command-line depending on the SDHCI probe ordering differences, and
it's work just fine for USB or other storage too.
