This patch fixes a bug introduced by commit "iwlwifi: adding MIMO3 support
in rate scaling". We should not set the dual_stream_ant_msk (for 2x2 MIMO)
when using a 3x3 rate, this will cause a SYSASSERT in uCode.

Note: there is no triple_stream_ant_msk, because all three antennas are used.

In the normal WPA or RSN case keys are only configured after

libertas: add support for Marvell SD8688 chip

Use RxPD->pkt_ptr to locate eth803 header in the packet
received since SD8688/v10 firmware allows a gap between
RxPD and eth803 header.

Set SDIO block size to 256 for CMD53.
The maximum block size for SD8688 WLAN function is set
to 512 in TPLFE_MAX_BLK_SIZE. But using 512 as block size
results upto 2K bytes data (4 blocks) being transferred
and causes buffer overflow in firmware.

Both changes above are backward compatible with earlier
firmware versions for SD8385/SD8686.

The SDIO_DEVICE_IDs for SD8688 chip are added in
include/linux/mmc/sdio_ids.h

in the TX path.  To improve throughput, ensure that the driver thread
has higher scheduling priority than the libertas main thread.  Do this
by making the libertas spi driver thread a low priority real time
thread.

We measured an average throughput improvement of 13%.
