UMP devices may have more interesting information than the traditional rawmidi. Extend the rawmidi_global_ops to allow the optional proc info output and show some more bits in the proc file for UMP. Note that the "Groups" field shows the first and the last UMP Groups, and both numbers are 1-based (i.e. the first group is 1).

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.
