media: rkvdec: Fix H264 scaling list order

The Rockchip Video Decoder driver is expecting that the values in a
scaling list are in zig-zag order and applies the inverse scanning process
to get the values in matrix order.

Commit 0b0393d59eb4 ("media: uapi: h264: clarify expected
scaling_list_4x4/8x8 order") clarified that the values in the scaling list
should already be in matrix order.

Fix this by removing the reordering and change to use two memcpy.
