Subject: [PATCH v2 0/6] media: mediatek: vcodec: support h264 extend vsi

The working buffer address start and end are calculated in kernel
side currently, can't calculate the address end if the driver only
getting the address file handle, not the real physical address. Need
to extend the vsi to calculate the address end in scp.

Re-construct some interface and add configuration to support extend
and non extend at the same time. Needn't to parse nal info for extend
architecture.
