Subject: [PATCH 5.18 0378/1095] media: mediatek: vcodec: Initialize decoder parameters after getting dec_capability

From: Yunfei Dong <yunfei.dong@...iatek.com>

[ Upstream commit faddaa735c208560a3f419038e8d154a01b584e3 ]

Need to get dec_capability from scp first, then initialize decoder
supported format and other parameters according to dec_capability value.

Fixes: fd00d90330d1 ("media: mtk-vcodec: vdec: move stateful ops into their own file")
