Flushing pending work items before resetting the device makes more sense than doing so afterwards. Some of them, like e.g. the NFC initialization one, find themselves with client IDs changed after the reset, eventually leading to trigger a client.c:mei_me_cl_by_id() warning after a few modprobe/rmmod cycles.

2013-04-08mei: bus: Add device enabling and disabling APISamuel Ortiz
It should be left to the drivers to enable and disable the device on the MEI bus when e.g getting probed. For drivers to be able to safely call the enable and disable hooks, the mei_cl_ops must be set before it's probed and thus this should happen before registering the device on the MEI bus. Hence the mei_cl_add_device() prototype change.

2013-03-29mei: rename function mei_hw_init to mei_startTomas Winkler
The hw initialization is now done as part of hw specific code this makes the name mei_hw_init little misleading. We rename it to mei_start in spirit of already existing functions mei_stop and mei_reset.

2013-03-29mei: ME structures should be initialized in mei_device_initTomas Winkler
mei_timer and mei_host_client_init belongs to mei framework and are not ME hw specific. AMTHIF and WD are available only for ME but are above the hardware layer so move the initialization back from mei_me_dev_init to mei_device_init.
