[Qemu-devel] [PATCH v3 06/16] xilinx: 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.

As QEMU_DPRINTF adds a header to the message, when the message is not in a new
line, printf has to be used.
