tipc: add read/write flashing lock state The new fastboot cmd need to store the flashing lock state in order to prevent flash. And the state is stored in rpmb. So the tipc provide the functions to read/write the flash_lock_state. Change-Id: Idf6eb7de7aff1b3257fcd70d0fc87ac7634de4d0 Signed-off-by: Jason Zhu <jason.zhu@rock-chips.com>
