mei: don't schedule suspend in pm idle
Calling pm_schedule_suspend from the runtime pm idle callback
may reschedule existing timer, thus in case of frequent runtime
rpm idle call the suspend maybe starved.
Instead we call pm_runtime_autosuspend which is checking if the
timer is already charged.
An example is monitoring device pci config space.
Pci config sysfs handlers calls pci_config_pm_runtime_put/get
helpers which in turns calls to device idle callback

NM and SPS FW types that may run on ME device on server platforms
do not have valid MEI/HECI interface and driver should not
be bound to it as this might lead to system hung.
In practice not all BIOSes effectively hide such devices from the
OS and in some cases it is not possible.
We determine FW type by examining Host FW status registers in order to
unbind the driver.

are trying to avoid nested resets
2. During initializations if the reset ended in MEI_DEV_DISABLED device
state we bail out with -ENODEV
3. Remove redundant interrupts_enabled parameter as this
can be deduced from the starting dev_state
4. mei_reset propagates error code to the caller
