wifi: ath12k: add factory test mode support

Add support to process factory test mode commands(FTM) for calibration.
By default firmware start with MISSION mode and to process the FTM commands
firmware needs to be restarted in FTM mode using module parameter ftm_mode.
The pre-request is all the radios should be down before starting the test.

All ath12k test mode interface related commands specified in enum
ath_tm_cmd.

When start command ATH_TM_CMD_TESTMODE_START is received, ar state
is set to test Mode and FTM daemon sends test mode command to wifi
driver via cfg80211. Wifi driver sends these command to firmware as
wmi events. If it is segmented commands it will be broken down into
multiple segments and encoded with TLV header else it is sent to
firmware as it is.

Firmware response via UTF events, wifi driver creates skb and send
to cfg80211, cfg80211 sends firmware response to FTM daemon via
netlink message.

Command to boot in ftm mode
insmod ath12k ftm_mode=1
