Move wl12xx and wl1251 modules into a new drivers/net/wireless/ti
directory. Add a TI WLAN Kconfig option and Makefile to support this
change.

Track freed FW blocks during Tx. If no blocks were freed during a
predefined timeout, initiate a HW recovery. This helps in situations
when the FW watchdog fails.
Don't trigger recovery during activities that can temporarily stop
Tx. This includes:
- scanning
- buffering packets for sleeping stations (AP role)
- ROC on any role

wl12xx currently looks for AP authorization by registering
a netdev notifier and waiting for the IF_OPER_UP notification,
which is quite cumbersome.
Use the newly introduced sta_state callback (waiting
for assoc -> auth notification) instead, in order to
simplify it.

wl12xx uses different fw for single-role and multi-role
scenarios (due to lack of space, some of the fw advanced
features are disabled in the multi-role fw).
Add checks on add_interfae and remove_interface in order
to determine whether a fw switch is needed (and initiate
recovery in this case).

Add multiple fw support by introducing a new fw_type member,

When configuring the arp response template,
and encryption is enabled, we should add some
space and set the protected flag bit in the fc.
In order to track the encryption type, set
wlvif->encryption_type when setting an encryption key,
and reconfigure the arp response. Clear this field on
wl1271_join, as keys have to be re-configured
anyway after a join command.
Similarly, track whether QoS is configured.

For certain WiFi certification tests forcing PS
is necessary. Since DPS is now enabled in the FW
and this can't be achieved by using netlatency
this required a new config option.

WLVIF_FLAG_PSM turned to WLVIF_FLAG_IN_AUTO_PS which
marks that this vif is in AUTO PS.
WLVIF_FLAG_PSM_REQUESTED is not required as mac80211
calls op_config with CONF_PS after association.
wl12xx_config_vif() handling of CONF_PS was simplified
and cleaned up.

The set_template commands now takes the role_id as
parameter.
Usually, we'll use the vif's main role_id.
However, sometimes we'll want to use
wlvif->dev_role_id instead of wlvif->role_id,
so pass the wanted role_id as param.
Update WL127X_FW_NAME/WL128X_FW_NAME.
(This commit starts a series of fw update patches,
and changes the start() callback to return an error
in order to prevent the use of the driver during the
transition. This change will be reverted in the
last patch of series)

Add support for two MAC addresses. If the NVS has a valid MAC
address, that takes precedence and we use two sequential address
starting from the one specified.
If the NVS doesn't contain a valid MAC address (ie. if it is set to
00:00:00:00:00:00), we check if the HW PG version in use has the
BD_ADDR written in the fuse ROM. If it does, we read it and derive
the two subsequent addresses for WLAN.
During production, 3 addresses are reserved per device. The first for
Bluetooth (burnt in the fuse ROM) and the following two for WLAN.
This patch has some code by Igal and Arik (squashed from internal
patches).

This flag should be set per-vif, rather than globally.
Rename the flag to indicate IN_USE (rather than IDLE), as
in the default configuration (i.e. flag is clear) the vif
should be idle.

SDIO blocksize alignment support is now the rule, not the exception.

Separate the debugging macros and other definitions to a new debug.h
file. This is be needed because the sdio and spi modules don't need
to depend on the wl12xx module anymore, but still need to include
wl12xx.h. Currently they do depend on it, because of the debugging
global that wl12xx exports. A future patch will remove this
dependency.
