Subject: [PATCH v1] mtk-vcodec: use V4L2_DEC_CMD_STOP to implement flush

From: Wu-Cheng Li <wuchengli@...gle.com>

This patch uses V4L2_DEC_CMD_STOP to implement flush -- requesting
the remaining images to be returned to userspace. The old unofficial
way was to use a size-0 input buffer and the code is removed.
