media: i2c: imx477: Replace existing 1012x760 mode

raspberrypi inclusion
category: feature
bugzilla: 50432

--------------------------------

The existing 1012x760 120 fps mode has significant IQ problem using
the internal sensor scaler. Replace this mode with a 1332x990 120 fps
mode instead. This new mode has a smaller field of view, but does not
suffer from the bad IQ of the original mode.
