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.
