[PATCH v2, 07/12] media: mtk-vcodec: Refactor supported vdec formats and framesizes

[Yunfei Dong <yunfei.dong@mediatek.com>]

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

Supported output and capture format types for mt8192 are different
with mt8183. Needs to get format types according to decoder capability.
