video: driver: alter stage, pipe setting sequence to avoid vcodec hung

Currently stage and pipe is configured from output port start/resume
sequence. During VSP processing FW has no clue about stage, so default
it picked 2 stage. Later host sets 1(due to < 720p) stage at output
port. VSP is already started operating on input frames. So this
mismatch in stage settings was leading to vcodec HW hung issues.

Setting STAGE, PIPE settings at input port start/resume to avoid
above mentioned issues.
