[PATCH v2 6/8] Bluetooth: Add Start Synchronization Train Command

[Dohyun Pyun <re20sfree@gmail.com>]

From: DoHyun Pyun <dh79.pyun@samsung.com>

The Start_Synchronization_Train command controls the Synchronization
Train functionality in the BR/EDR Controller.

The Core Spec Addendum 4 adds this command in part B Connectionless
Slave Broadcast.

Bluetooth Core Specification Addendum 4 - Page 86

"7.1.51 Start Synchronization Train Command [New Section]
...
If connectionless slave broadcast mode is not enabled, the Command
Disallowed (0x0C) error code shall be returned. After receiving this
command and returning a Command Status event, the Baseband starts
attempting to send synchronization train packets containing information
related to the enabled Connectionless Slave Broadcast packet timing.

Note: The AFH_Channel_Map used in the synchronization train packets is
configured by the Set_AFH_Channel_Classification command and the local
channel classification in the BR/EDR Controller.

The synchronization train packets will be sent using the parameters
specified by the latest Write_Synchronization_Train_Parameters command.
The Synchronization Train will continue until synchronization_trainTO
slots (as specified in the last Write_Synchronization_Train command)
have passed or until the Host disables the Connectionless Slave Broadcast
logical transport."
