This patch enables CONFIG_BLK and some DM enabled drivers on clearfog
to remove these compile warnings:

===================== WARNING ======================

the board to use CONFIG_DM_MMC before the v2019.04 release.
Failure to update by the deadline may result in board removal.
See doc/driver-model/MIGRATION.txt for more info.
====================================================
===================== WARNING ======================
This board does not use CONFIG_DM_USB. Please update
the board to use CONFIG_DM_USB before the v2019.07 release.

====================================================
===================== WARNING ======================
