drm/panel: Fine tune Starry-ili9882t panel HFP and HBP

Because the setting of hporch is too small, there will be warning in
kernel log[1]. After fine tune the HFP and HBP, this warning can be
solved. The actual measurement frame rate is 60.1Hz.

[1]: WARNING kernel:[drm] HFP + HBP less than d-phy, FPS will under 60Hz
