The stop_hw trans callback is not well defined. It is missing in many
cleanup flows and the division of labor between stop_device/stop_hw
is cumbersome. Remove stop_hw and use stop_device to perform both.
Implement this for all current transports.
PCIE needs some extra configuration the op-mode is leaving to configure
RF kill. Expose this explicitly as a new op_mode_leave trans callback.
Take the call to stop_device outside iwl_run_mvm_init_ucode, this
makes more sense and WARN when we want to run the INIT firmware while
it has run already.

Send firmware a Smart FIFO Configuration host command to allow
interrupt coalescing. The smart FIFO is enabled when there is
only one bound interface (other than p2p devices which are
ignored) and it is of type station, and activated while the
station is associated.
Smart Fifo allows aggragations of DMA transactions and by that
causes processor and memory controller to stay for a longer time
on lower c-states, thus saving platform power.
Firmware relies on driver to activate and disable it.

If the firmware image that we attempt to load doesn't
actually exist we have a broken firmware file or other
code not checking things correctly, so warn in such a
case. Also avoid assigning cur_ucode/ucode_loaded then.

Some NICs aren't allowed to be powered up at driver load time.
Fix it, and move the external NVM loading from driver load time to
driver up time (parsing the external nvm file remains at driver load time).

FW starts using legacy power table command (0x77) for device wide power
settings. Currently this command contains only option flags field.
It can configure the following: CAM (Continuous Active Mode) and
POWER_SAVE_ENABLE debug option. Send this command when firmware is
loaded - D0 and D3.
Note: Setting this command is important to avoid unwanted FW behavior.
It particularly fixes a bug when a device does not drop to low power
after disassociation from AP.

In RF KILL the init ucode is running, but don't complete
all its tasks, so we need to run the init ucode again.
Change the flag name to init_ucode_complete, to be more appropriate.

In order to avoid NIC destruction due to high temperature,
CT kill will power down the NIC.
To avoid this, thermal throttling will decrease throughput
to prevent the NIC from reaching the temperature at which
CT kill is performed.

If RF-kill is asserted while a device is initialized, the
firmware INIT image can now be run to retrieve the NVM
data and register to mac80211 properly. Previously, the
initialisation would fail in this scenario and the driver
wouldn't register with mac80211 at all, making the device
unusable.

1. All the phy contexts are added immediately after the
firmware is loaded and up.
2. Whenever a PHY context needs to be used, its reference
counter is incremented and the PHY context is being
configured to the appropriate configuration.
3. When a PHY context is no longer needed, its reference
count is decremented.
4. PHY contexts are never removed.
