Moved, renamed, and deleted files
The original directory structure was scattered and unorganized. Changes are basically to make it look like kernel structure.

-/**
- * DOC: Operational mode - what is it ?
- *
- * The operational mode (a.k.a. op_mode) is the layer that implements
- * mac80211's handlers. It knows two APIs: mac80211's and the fw's. It uses
- * the transport API to access the HW. The op_mode doesn't need to know how the
- * underlying HW works, since the transport layer takes care of that.
- *
- * There can be several op_mode: i.e. different fw APIs will require two
- * different op_modes. This is why the op_mode is virtualized.
- */
-
-/**
- * DOC: Life cycle of the Operational mode
- *
- * The operational mode has a very simple life cycle.
- *
- * 1) The driver layer (iwl-drv.c) chooses the op_mode based on the
- * capabilities advertized by the fw file (in TLV format).
- * 2) The driver layer starts the op_mode (ops->start)
- * 3) The op_mode registers registers mac80211
- * 4) The op_mode is governed by mac80211
- * 5) The driver layer stops the op_mode
- */
-
-/**
- * struct iwl_op_mode_ops - op_mode specific operations
- *
- * The op_mode exports its ops so that external components can start it and
- * interact with it. The driver layer typically calls the start and stop
- * handlers, the transport layer calls the others.
- *
- * All the handlers MUST be implemented
- *
- * @start: start the op_mode. The transport layer is already allocated.
- * May sleep
- * @stop: stop the op_mode. Must free all the memory allocated.
- * May sleep
- * @rx: Rx notification to the op_mode. rxb is the Rx buffer itself. Cmd is the
- * HCMD the this Rx responds to.
- * Must be atomic.
- * @queue_full: notifies that a HW queue is full. Ac is the ac of the queue
- * Must be atomic
- * @queue_not_full: notifies that a HW queue is not full any more.
- * Ac is the ac of the queue. Must be atomic
- * @hw_rf_kill:notifies of a change in the HW rf kill switch. True means that
- * the radio is killed. Must be atomic.
- * @free_skb: allows the transport layer to free skbs that haven't been
- * reclaimed by the op_mode. This can happen when the driver is freed and
- * there are Tx packets pending in the transport layer.
- * Must be atomic
- * @nic_error: error notification. Must be atomic
- * @cmd_queue_full: Called when the command queue gets full. Must be atomic.
- * @nic_config: configure NIC, called before firmware is started.
- * May sleep
