Subject: [PATCH 2/7] media: venus: venc: set correct resolution on compressed stream

This change the alignment restriction for output type of buffers
only, also set corect input resolution and fill bidirectional
vb2 queue flag in order to map output type buffers read/write.
The last is needed by encoder firmware to add padding at the
bottom of output (input buffers).
