MLK-3056-2 drm/panel: rm67191: change clock rate to 121MHz for default mode

Browse Source 
The latest batch of RM67191 panels have an issue that the panel display
will get blurred and have no response to later display actions when read
data from panel through DSI interface.

And decrease the pixel clock rate to 121MHz which means decrease the
panel's frame rate from 60.02Hz to 55.02Hz can solve this issue, so
do this change to make RM67191 display more stable.
