Subject: [char-misc-next] mei: drop unused hw dependent fw status functions
From: Alexander Usyskin <alexander.usyskin@...el.com>
We introduced unified FW status function in patch
mei: add per device configuration (lkml.org/lkml/2014/5/12/607)
This change made hw_ops functions unused and obsolete
therefore we remove these functions from source code.
