habanalabs: Make the Coresight timestamp perpetual
The Coresight timestamp is enabled for a specific debug session using the HL_DEBUG_OP_TIMESTAMP opcode of the debug IOCTL. In order to have a perpetual timestamp that would be comparable between various debug sessions, this patch moves the timestamp enablement to be part of the HW initialization. The HL_DEBUG_OP_TIMESTAMP opcode turns to be deprecated and shouldn't be used. Old user-space that will call it won't see any change in the behavior of the debug session.
