[PATCH 04/14] media: mediatek: vcodec: initialize msg and vsi information

[Yunfei Dong <yunfei.dong@xxxxxxxxxxxx>]

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.
