Well, since CONFIG_SPL_DM_USB depends on SPL_DM_USB, I don’t think that’s the case.

Aha! There are two reasons I did this:
1) I used CONFIG_SPL_DM_MMC as the inspiration for my changes. That one depends on CONFIG_DM_MMC.
2) In order to not break a lot of configs, see above.

If this is unacceptable for you, I guess, I’ll have to revisit this. That’d make this series a lot bigger I think. Tell me your preference.
