Currently we're only dumping out the ddb allocation changes, let's do the same for the watermarks. This should help with debugging underruns and whatnot. First I tried one line per plane per wm level, but that resulted in an obnoxious amount of lines printed. So as a compromise I settled on a four line format, each line containing a single watermark related value (enable,lines,blocks,min_ddb_alloc) for all 8 levels (+trans wm). It still produces quite a lot of output but I can't really see a way around that because we simply have a lot of data to dump. Let's also pimp the ddb debug to print the size of the allocations too, not just their bounds. Makes it a bit easier to compare against the watermarks.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
