This reverts commit 40892b0c08fbc8029921e91511dd3f91fc956f90. The feature of returning progress for libflashrom users was introduced in original commit, however later a bug was found and reported as https://ticket.coreboot.org/issues/390. Reverting in a release branch to unblock release candidate, since it is unknown how much time needed to fix the bug. Meanwhile the feature remains in a master branch and will be fixed under ticket 390.
