So, a problem with this patch is that we can't only enable CONFIG_BLK in
all cases, we also need to make sure that if we have MMC we have DM_MMC
and if we have USB we have DM_USB.  This latter case is what tripped me
up as am43xx_evm_usbhost_boot_defconfig will have a warning with this
patch applied as SPL_USB_SUPPORT really requires CONFIG_USB_STORAGE
support and that in turn depends on either (BLK==n && DM_USB==n) or
(BLK==y && DM_USB==y).
