libertas: [sdio] use common firmware request helper and new firmware locations
linux-firmware puts libertas firmware in /libertas. Fix the driver to
look there first, but fall back to the old firmware names if the new
ones don't exist. Add preference for newer firmware versions too.

libertas: Add auto deep sleep support for SD8385/SD8686/SD8688
Add timer based auto deep sleep feature in libertas driver which can be
configured using iwconfig command. This is tested on SD8688, SD8686 cards
with firmware versions 10.38.1.p25, 9.70.4.p0 respectively on 32-bit and 64-bit
platforms. Tests have been done for USB/CS cards to make sure that the patch
won't break USB/CS code. We didn't test the if_spi driver.

libertas: read SD8688 firmware status from new register
The scratch pad register is used to store firmware status after
firmware is downloaded and initialized. After firmware status is
verified OK, the same register is used to store RX packet length.
Hence the firmware status code is no longer valid afterwards.
SD8688 firmware introduces a new register for firmware status
which will never be overwritten.
Also add scratch_reg variable to if_sdio_card structure and
initialize it based on the model of the card during probe.

libertas: get SD8688 rx length with one CMD52
Usually, the 16-bit rx length is read from scratch pad registers
with two CMD52 transactions:
SD8385: IF_SDIO_SCRATCH_OLD (0x80fe/0x80ff)
SD8686/SD8688: IF_SDIO_SCRATCH (0x34/0x35)
Alternatively, SD8688 firmware offers an enhanced method for driver
to read an 8-bit rx length (in units) with a single CMD52:
IF_SDIO_RX_UNIT 0x43 is read one time after firmware is ready.
IF_SDIO_RX_LEN 0x42 is read every time when rx interrupt is received.

libertas: add support for Marvell SD8688 chip
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

libertas: move to uniform lbs_/LBS_ namespace
This patch unifies the namespace of variables, functions defines
and structures. It does:
- rename libertas_XXX to lbs_XXX
- rename LIBERTAS_XXX to lbs_XXX
- rename wlan_XXX to lbs_XXX
- rename WLAN_XXX to LBS_XXX (but only those that were
defined in libertas-local *.h files, e.g. not defines
from net/ieee80211.h)
While passing, I fixed some checkpatch.pl errors too.
