configs: am335x_boneblack_vboot_defconfig: Fix regression by enabling BLK and DM...

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).
