[media] adv7604/adv7842: fix quantization range handling
Fix a number of bugs that appeared when support for mediabus formats was added: - Support for V4L2_DV_RGB_RANGE_FULL/LIMITED should only be enabled for HDMI RGB formats, not for YCbCr formats. Since, as the name says, this setting is for RGB only. So read the InfoFrame to check the format. - the quantization range for the pixelport depends on whether the mediabus code is RGB or not: if it is RGB, then produce full range RGB values, otherwise produce limited range YCbCr values. This means that the op_656_range and alt_data_sat fields of the platform data are no longer used and these will be removed in a following patch. - when setting up a new format the RGB quantization range settings were never updated. Do so, since this depends on the format. - fix the log_status output which was confusing and incorrect.
