drm/i915: Set up PIPE_MISC truncate bit on tgl+
Looks like the pipe rounding mode bit has moved from PIPE_CHICKEN to PIPE_MISC on tgl. Frob the new location. Bspec does still document the old bits as well, so I left the code for them as is until we get clarification from the hw folks on whether the old bits still do something useful.
