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. -Daniel
