commit 2e4b2ec9d440fc03cb87713ecc45c99f4bdca690
Author: Aaron Durbin

Revert "cbfstool: Add 'hashcbfs' command to compute hash of CBFS region."

This reverts commit 272a1f05b943d781acb8c04c01874bde9df3b774.

In Chrome OS this command's usage was dropped in favor of another
    solution. As it's not used drop the support for it.
