Subject: [PATCH v2,11/21] media: mediatek: vcodec: initialize msg and vsi information
Need to initialize msg and vsi information before sending to optee-os, then
calling optee invoke command to send the information to optee-os.
For the optee communication interface is different with scp, using
flag to separate them.
