[PATCH v3 12/14] media: mediatek: vcodec: send share memory address to vcp

[Yunfei Dong <yunfei.dong@mediatek.com>]

The share memory is allocated in kernel for vcp architecture, it's different
with vpu which share memors is reserved in vpu micro processor. Need to send
share memory address to vcp.
