Guillaume Martres faf03ecba0 hevc: Remove useless clip
The src buffer should only contain values in the interval
[0, (1 << BIT_DEPTH) - 1].

Since shift = (BIT_DEPTH - 5), src[x] >> shift must be in
the interval [0, 31], so no clip is needed.

Guillaume Martres a246d06fe0 hevc: clip pixels when transquant bypass is used
The reconstructed picture should always be clipped (see section 8.6.5),
previously we did not clip coding units where
cu_transquant_bypass_flag == 1.

Guillaume Martres b00a8b4d19 hevc: remove useless clip in FUNC(sao_band_filter)()
The src buffer should only contain values in the interval
[0, (1 << BIT_DEPTH) - 1]. Since shift = (BIT_DEPTH - 5), src[x] >> shift
must be in the interval [0, 31], so no clip is needed.

This removes the code that was changed in 5856bca360
as the clip that was repositioned in that commit is removed

This is a more proper fix than 5856bca360
