blk: Support block drivers in TPL

At present it is not possible to enable/disable block drivers in TPL. This
is needed to provide sandbox support. Add a Kconfig option and adjust the
Makefile.

Enable support for block devices, such as SCSI, MMC and USB
flash sticks. These provide a block-level interface which permits
reading, writing and (in some cases) erasing blocks. Block
devices often have a partition table which allows the device to
be partitioned into several areas, called 'partitions' in U-Boot.
A filesystem can be placed in each partition.
