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 "support mt8186 decoder"[1]
