drm/radeon: reset i2c valid to avoid incorrect tv-out polling. 



We really don't want to be polling tv-out but since we weren't forcing the
i2c lines to invalid (tv-out has no DDC), we were adding tv connectors to the
polling setup and this was causing blinking on secondary displays.

This fixes the regression Torsten reported.
