drm/bridge/synopsys: dsi: use adjusted_mode in mode_set

Browse source

The "adjusted_mode" clock value (ie the real pixel clock) is more
accurate than "mode" clock value (ie the panel/bridge requested
clock value). It offers a better preciseness for timing
computations and allows to reduce the extra dsi bandwidth in
burst mode (from ~20% to ~10-12%, hw platform dependent).
