This patch adds BLK and DM support for verified boot on TI AM335x chipsets. The following compile warnings are removed:

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

BLK and DM_MMC are enabled by default in SPL as well, which is making the build to break with an overflow(spl image doesn't fit into SRAM because of size constraints).

LD spl/drivers/built-in.o LD spl/u-boot-spl arm-linux-ld.bfd: u-boot-spl section .u_boot_list will not fit in region .sram arm-linux-ld.bfd: region .sram overflowed by 116 bytes make[1]: *** [spl/u-boot-spl] Error 1 make: *** [spl/u-boot-spl] Error 2

For the above reason BLK and DM_MMC is disabled in SPL. Built and tested on AM335x device (BeagleboneBlack).
