Daniel Vetter 1062b81598 drm/i915/tv: clear adjusted_mode.flags
The native TV encoder has it's own flags to adjust sync modes and
enabled interlaced modes which are totally irrelevant for the adjusted
mode. This worked out nicely since the input modes used by both the
load detect code and reported in the ->get_modes callbacks all have no
flags set, and we also don't fill out any of them in the ->get_config
callback.

This changed with the additional sanitation done with

    drm/i915: make user mode sync polarity setting explicit

sinc now the "no flags at all" state wouldn't fit through core code
any more. So fix this up again by explicitly clearing the flags in the
->compute_config callback.

Aside: We have zero checking in place to make sure that the requested
mode is indeed the right input mode we want for the selected TV mode.
So we'll happily fall over if userspace tries to pull us.  But that's
definitely work for a different patch series. So just add a FIXME
comment for now.
