Hi Chen-Yu,

The rkvdec H.264 decoder currently overrides sizeimage for the output format. This causes issues when userspace requires and requests a larger buffer, but ends up with one of insufficient size.
Instead, only provide a default size if none was requested. This fixes the video_decode_accelerator_tests from Chromium failing on the first frame due to insufficient buffer space. It also aligns the behavior of the rkvdec driver with the Hantro and Cedrus drivers.
