In order to support secure video decoder for mt8195/mt8188 h264 driver,
need to use tee client interface to communicate with optee-os. Firstly,
open tee context and tee session for each hardware.
Secondly, allocate two shared memory msg and vsi, msg used to send ipi to
optee-os and get ack msg from optee-os, vsi used to store syntax for
hardware decoder.
Thirdly, adding two CID controls: V4L2_CID_MPEG_MTK_SET_SECURE_MODE and
V4L2_CID_MPEG_MTK_GET_SECURE_HANDLE, get secure handle used for user space
to convert secure fd to secure handle, set secure mode used to tell decoder
driver to initialize tee interface to decode secure video.
Lastly, re-construct h264 driver to support secure video decoder.
Patch 1~4 initialize tee related interface and parameters.
Patch 5~6 allocate/free secure memory.
Patch 7 map vsi for secure mode.
Patch 8 support one plane capture buffer.
Patch 9~10 re-construct h264 driver to support secure mode.
patch 11 used to convert secure fd to secure handle.
Patch 12 used to set secure decoder mode.
Patch 13 disable interrupt.
Patch 14 support tee decode
