Subject: [PATCH AUTOSEL 6.0 13/34] media: hantro: HEVC: Fix chroma offset computation

From: Benjamin Gaignard <benjamin.gaignard@...labora.com>

[ Upstream commit f64853ad7f964b3bf7c1d63b27ca7ef972797a1c ]

The chroma offset depends of the bitstream depth.
Make sure that ctx->bit_depth is used to compute it.
