iwlwifi: mvm: Add Smart FIFO support
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.
