Avri Altman 002a9e2677 iwlwifi: trans: configure the scheduler enable register 
Currently the firmware is handling this, but that is wrong as it then
needs to assume a certain command queue, therefore this should be in
the driver; add it here so it can be removed from the firmware in the
future.

/**
* Tx Scheduler
*
* The Tx Scheduler selects the next frame to be transmitted, choosing TFDs
* (Transmit Frame Descriptors) from up to 16 circular Tx queues resident in
* host DRAM. It steers each frame's Tx command (which contains the frame
* data) into one of up to 7 prioritized Tx DMA FIFO channels within the
* device. A queue maps to only one (selectable by driver) Tx DMA channel,
* but one DMA channel may take input from several queues.
*
* Tx DMA FIFOs have dedicated purposes.
*
* For 5000 series and up, they are used differently
* (cf. iwl5000_default_queue_to_tx_fifo in iwl-5000.c):
*
* 0 -- EDCA BK (background) frames, lowest priority
* 1 -- EDCA BE (best effort) frames, normal priority
* 2 -- EDCA VI (video) frames, higher priority
* 3 -- EDCA VO (voice) and management frames, highest priority
* 4 -- unused
* 5 -- unused
* 6 -- unused
* 7 -- Commands
*
* Driver should normally map queues 0-6 to Tx DMA/FIFO channels 0-6.
* In addition, driver can map the remaining queues to Tx DMA/FIFO
* channels 0-3 to support 11n aggregation via EDCA DMA channels.
*
* The driver sets up each queue to work in one of two modes:
*
* 1) Scheduler-Ack, in which the scheduler automatically supports a
* block-ack (BA) window of up to 64 TFDs. In this mode, each queue
* contains TFDs for a unique combination of Recipient Address (RA)
* and Traffic Identifier (TID), that is, traffic of a given
* Quality-Of-Service (QOS) priority, destined for a single station.
*
* In scheduler-ack mode, the scheduler keeps track of the Tx status of
* each frame within the BA window, including whether it's been transmitted,
* and whether it's been acknowledged by the receiving station. The device
* automatically processes block-acks received from the receiving STA,
* and reschedules un-acked frames to be retransmitted (successful
* Tx completion may end up being out-of-order).
*
* The driver must maintain the queue's Byte Count table in host DRAM
* for this mode.
* This mode does not support fragmentation.
*
* 2) FIFO (a.k.a. non-Scheduler-ACK), in which each TFD is processed in order.
* The device may automatically retry Tx, but will retry only one frame
* at a time, until receiving ACK from receiving station, or reaching
* retry limit and giving up.
*
* The command queue (#4/#9) must use this mode!
* This mode does not require use of the Byte Count table in host DRAM.
*
* Driver controls scheduler operation via 3 means:
* 1) Scheduler registers
* 2) Shared scheduler data base in internal SRAM
* 3) Shared data in host DRAM
*
* Initialization:
*
* When loading, driver should allocate memory for:
* 1) 16 TFD circular buffers, each with space for (typically) 256 TFDs.
* 2) 16 Byte Count circular buffers in 16 KBytes contiguous memory
* (1024 bytes for each queue).
*
* After receiving "Alive" response from uCode, driver must initialize
* the scheduler (especially for queue #4/#9, the command queue, otherwise
* the driver can't issue commands!):
