[U-Boot] [PATCHv2] blk: Make use of CONFIG_HAVE_BLOCK_DEVICE more

[Tom Rini]

When we do not have CONFIG_BLK (or SPL/TPL) enabled there are very few
cases where we need the blk_legacy code linked in. To catch these, build
when we have CONFIG_HAVE_BLOCK_DEVICE set.  In addition, we only need
cmd/blk_common.o to be linked in when we have CONFIG_HAVE_BLOCK_DEVICE
set, so make use of that directly.

Changes in v2:
- Reword commit message and make blk_legacy.o also use
  CONFIG_HAVE_BLOCK_DEVICE rather than CONFIG_PARTITIONS as it is more
  direct.
