media: uapi: h264: Further clarify scaling lists order
Commit 0b0393d59eb4a ("media: uapi: h264: clarify expected scaling_list_4x4/8x8 order") improved the documentation on H264 scaling lists order. This commit improves the documentation by clarifying that the lists themselves are expected in raster scan order.
