[PATCH AUTOSEL 6.0 12/34] media: hantro: HEVC: Fix auxilary buffer size calculation

[Sasha Levin]

From: Benjamin Gaignard <benjamin.gaignard at collabora.com>

[ Upstream commit 8a438580a09ecef78cd6c5825d628b4d5ae1c127 ]

SAO and FILTER buffers size depend of the bit depth.
Make sure we have enough space for 10bit bitstreams.
