drm/i915/dsi: Add vblank calculation for command mode

Browse source

Transcoder timing calculation differ for command mode.

v2: Use is_vid_mode, and use same I915_WRITE (Jani)
v3: Adjust the calculations to reflect dsc compression ratio
v4: Rearrange the vertical and horizontal timing calc, optimize
    local variables usage. (Jani)
v5: Fix the values used for calculation, use afe_clk for
    byte clock calculation, use intel_de_write/read (Jani)
