Interesting because the config bits don't appear to have changed:

CONFIG_MMC_OMAP=m
CONFIG_MMC_OMAP_HS=y

These two bits are the same on both kernels, maybe some more generic
config that's been moved around that's causing the regression.

So surely that's a bug in dracut that needs to detect that the module
is needed for booting.
