[PATCH v2 08/12] media: rkvdec: h264: Use bytesperline and buffer height to calculate stride

Use bytesperline and buffer height to calculate the strides configured.

This does not really change anything other than ensuring the bytesperline
that is signaled to userspace matches what is configured in HW.
