drm/msm/dpu: drop TE2 definitions

Neither DPU driver nor vendor SDE driver do not use TE2 definitions
(and, in case of SDE driver, never did). Semantics of the TE2 feature
bit and .te2 sblk are not completely clear. Drop these bits from the
catalog with the possibility of reintroducing them later if we need to
support ppsplit.
