Subject: [PATCH v2, 05/12] media: mtk-vcodec: Call v4l2_m2m_set_dst_buffered() set capture buffer buffered

From: Yunfei Dong <yunfei.dong@...iatek.corp-partner.google.com>

For lat and core architecture, just need to get output buffer for lat
decode. For core hardware need to get lat's message and capture buffer.
In order to let lat and core decode in parallel, need to set capture
buffer buffered.
