Jani Nikula 6b20ea56dd drm/i915/dsi: don't pass arbitrary data to sideband 
[ Upstream commit 26f6f2d301 ]

Since sequence block v2 the second byte contains flags other than just
pull up/down. Don't pass arbitrary data to the sideband interface.

The rest may or may not work for sequence block v2, but there should be
no harm done.
