Subject: [PATCH 2/3] staging: media: max96712: enable extra debug register for max96724

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.
