[PATCH v2, 02/12] media: mtk-vcodec: Using firmware type to separate different firmware architecture

[Yunfei Dong]

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

MT8173 platform use vpu firmware, mt8183/mt8192 will use scp
firmware instead, using chip name is not reasonable to separate
different firmware architecture. Using firmware type is much better.
