drivers/analogix/anx7625: prevent video clock jitter on IVO panels
The MIPI source video data has a large variation (e.g. 59Hz ~ 61Hz),
anx7625 defines K ratio for matching MIPI input video clock and
DP output video clock. A bigger k value can match a bigger video data
variation. IVO panel has smaller variation than DP CTS spec, so decrease
k value to 0x3b.
