Instead of constructing the FourCC code manually, use the %p4cc printk
modifier to print it. Also leave a message to avoid using this function.
The next step would be to convert the users to use %p4cc directly instead
and removing the function.

I think would be nice if we could roll this out and outright delete
this one here ... Quick git grep says there's not that many, and %p4cc
is quite a bit shorter than what we have now.
Sounds good; I can submit patches for that but I think I'll do that once we
have the %p4cc modifier in.
