drm/i915/dsi: Move calling of wait_for_dsi_fifo_empty to mipi_exec_send_packet

Browse Source 
Instead of calling wait_for_dsi_fifo_empty on all dsi ports after calling
a drm_panel_foo helper which calls VBT sequences, move it to the VBT
mipi_exec_send_packet helper, which is the one VBT instruction which
actually puts data in the fifo.

This results in a nice cleanup making it clearer what all the steps on
intel_dsi_enable / disable are and this also makes the VBT code properly
wait till a command has actually been send before executing the next
steps (typically a delay) in the VBT sequence.
