[Qemu-devel] [PATCH v3 11/16] rc4030: Convert debug printfs to QEMU_DPRINTF

["Marc Marí" <marc.mari.barcelo@gmail.com>]

Modify debug macros to have the same format through the codebase and use regular
ifs instead of ifdef.

Change the output of debug messages from stdout to stderr.

Remove header in debug printfs, as QEMU_DPRINTF already adds it.
