The current implementation has the register disabled since it is not documented in the MAX96724 RM. However, in the chip's user's guide [1], in the Video Pattern Generator section, the register is documented and it appears to work just fine. Before the change I was experiencing approx 10fps when streaming, after: 30.3fps. Hence, since both max96712 and max96724 have the register, we can remove the flag.
