drm: samsung: update underrun and cmd_te ctl when fps is changed
DSIM_UNDERRUN_CTRL, DSIM_CMD_TE_CTRL0 and DSIM_CMD_TE_CTRL1 need to be
updated base on fps when refresh rate is changed to make underrun
detection work correctly.
Calculate underrun_lp_ref at runtime based on current refresh rate if
cmd_underrun_cnt is not specified.
Bug: 174830564
Test: enable `Smooth Display` do some test without noise rectangle noise
and underrun occurs. Test includes launch apps, scrolling, video
playing, youtube, suspend/resume, rotation, AoD
Test: limit DISP max clock to reproduce noise rectangle symptom and
check underrun count keep increasing
