Hardware can parse the slice syntax to get nal information in
scp for extend architecture, needn't to parse it again in
kernel.

Squash this in with the other "add extended architecture" patches.
You are removing code that you just added. So why add it in the
first place?

You can just mention in the commit message that the new architecture
can parse the slice syntax directly.
