drm/radeon: use raw buffer printk specifier

printk format strings accepting a single subsequent argument
are shorter thus easier to read.

Instead of having format strings accepting 3 different arguments
pointing to first 3 bytes of the same buffer rewrite the format
string to accept only one argument - the buffer - with "%3ph"
specifier.
