Jani Nikula f90e8c36c8 drm/i915/dsi: fix bxt split screen and color issue
Fix the failure mode where the display appears split, or shifted about
2/3 of the screen, and the color components are cycled. Turns out we
were missing the crucial BXT_DEFEATURE_DPI_FIFO_CTR bit in the
EOT_DISABLE register.

Per bspec, with the bit set, the "mipi_dpf_vblank_start" signal is
asserted only when the complete frame is transferred in the DPHY line
and also the DPI FIFO is flushed out at the end of each frame.

The problem was mitigated by keeping the panel fitter enabled, but that
only limited the issue to a shift of about 0..10 pixels. With the fix
here, the panel fitter workaround does not seem to be needed at all.

While at it, set BXT_DPHY_DEFEATURE_EN in EOT_DISABLE register which is
also needed per the BXT DSI mode set sequence.
