drm/bridge: synopsys: dw-mipi-dsi: Fix hcomponent lbcc for burst mode

In order to support burst mode, vendor drivers set lane_mbps higher than
bandwidth through DPI interface.  So, calculate horizontal component lane
byte clock cycle(lbcc) based on lane_mbps instead of pixel clock rate for
burst mode.
