MLK-20242: drm/imx/dcss: fix brightness for REC.709

The brightness, when REC709 was used in the configuration of the pipes,
was lower than expected.

The reason was the HDR10 configuration application that was used to
create the tables had a parameter that was wrongly set.

The tables were re-generated with the proper setting.
