Subject: [PATCH v6, 0/7] support mt8195 decoder

Firstly, add mt8195 soc lat hardware and compatible, then add documents.
For vp8 only support MM21 mode, H264/vp9 support MT21C, need to separate
them. Lastly, enable H264 inner racing mode to reduce hardware latency.

Patch 1~4 add mt8195 soc lat hardware and compatible, then add documents.
Patch 5 using different format for different codecs.
Patch 6 prevent kernel crash when scp reboot.
Patch 7 enable H264 inner racing mode to reduce hardware latency.

This patch depends on "add h264 decoder driver for mt8186"[1]
