blk: Make functions available unconditionally

Some boards still don't enable BLK but we want to be able to at least
compile the code which relies on this. For example, bootstd includes
calls to blk_...() functions, albeit with a check for BLK so that the
code is eliminated by the compiler.

Reduce the scope of the BLK #ifdef to help with this.
