mac80211: support secondary channel offset in CSA

Add support for the secondary channel offset IE in channel
switch announcements. This is necessary for proper handling
of CSA on HT access points.

For this to work it is also necessary to convert everything
here to use chandef structs instead of just channels. The
driver updates aren't really correct though. In particular,
the TI wl18xx driver update can't possibly be right since
it just ignores the new channel width for lack of firmware
API.

wlcore: update channel_switch/stop_channel_switch commands

Some fields were added to the channel_switch and
stop_channel_switch commands. Unfortunately,
the new 18xx channel_switch struct is not backward
compatible with the 12xx channel switch struct.

Add a new channel_switch op to wlcore, and update
the driver accordingly.

wlcore/wl12xx: calibrator fem detect implementation

this completes the calibrator based fem detect logic in driver:
driver starts (by calibrator) in plt_mode PLT_FEM_DETECT
wlcore inits and starts plt on wl12xx
wl12xx fetches fem number from firmware and stores it in wl->fem_manuf
wl12xx immediatly returns (doesn't start radio, etc...)
wlcore returns the fem_manuf to calibrator using WL1271_TM_ATTR_DATA
plt_mode is stopped

wlcore/wl12xx: add support for HP and SKW FEM radio manufacturers

Add support for HP (High Performance TQS fem type 3) and SKW
(fem type 2). This is done by increasing the number of FEM
manufacturers to 4.

Usually FEM parameters from ini file are read from nvs file and
passed to firmware using TEST_CMD_INI_FILE_RADIO_PARAM. Still,
because the nvs file has only place for 2 FEMs, we need to pass the
new FEM types information in one of the available entries.

This is done by mapping new fem types 2,3 to entry 0. This solution
works for manual FEM selection. AutoDetect-FEM still support only
fem types 0 and 1.

wlcore/wl12xx: move ref_clock and tcxo_clock elements to wl12xx

Only wl12xx needs to get the ref_clock anc tcxo_clock values from the
platform data. Move these elements from the wl1271 structure to
wl12xx's private data.

wlcore/wl12xx: move extended radio configuration parameters to wl12xx

The extended radio configuration parameters are only used by the
wl127x chipsets, which are handled by the wl12xx driver. Move the rf
configuration settings from wlcore to wl12xx.

wlcore/wl12xx: add hw_init operation

Move all the wl12xx-specific hw initialization procedures into a new
hw_init op. Move some commands and ACX functions to wl12xx.

wireless/wl12xx/wl1251: move TI WLAN modules to a common ti subdirectory

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.
