[PATCH] drm/i915/display: Don't program DBUF_CTL tracker state service

[Ravi Kumar Vodapalli]

While display initialization along with MBUS credits programming
DBUF_CTL register is also programmed, as a part of it the tracker
state service field is also set to 0x8 value when default value is
other than 0x8 which are for platforms past display version 13.
For remaining platforms the default value is already 0x8 so don't
program them.
