drm/xe/xe3p_lpg: Add missing references to workarounds

Browse Source 
Sometimes the same workaround implementation ends up being the
recommended fix different hardware issues, which are tracked by
different workaround lineage numbers.

Some of the Xe3p_LPG workarounds got "dismissed" because the
implementations were already in the driver, however for a different
lineage number.

Even though the implementation for workaround #A is already present in
the driver for workaround #B, it is still important to reference #A in
the driver for tracking purposes.  Without such a reference, we risk
dropping the workaround implementation if, for some reason in the
future, we decide that #B is not necessary anymore while #A is still
required.

As such, add the missing references for Xe3p_LPG.
