The configuration for mt8192 was incorrectly using the output formats
from mt8173. Since the output formats for mt8192 are instead the same
ones as for mt8183, which require two bus samples per pixel, the
pixelclock and DDR edge setting were misconfigured. This made external
displays unable to show the image.
Fix the issue by correcting the output format for mt8192 to be the same
as for mt8183, fixing the usage of external displays for mt8192.
