Hans de Goede c9121cf637 HID: logitech-dj: add support for 27 MHz receivers
Most Logitech wireless keyboard and mice using the 27 MHz are hidpp10
devices, add support to logitech-dj for their receivers.

Doing so leads to 2 improvements:

1) All these devices share the same USB product-id for their receiver,
making it impossible to properly map some special keys / buttons
which differ from device to device. Adding support to logitech-dj to
see these as hidpp10 devices allows us to get the actual device-id
from the keyboard / mouse.

2) It enables battery-monitoring of these devices

This patch uses a new HID group for 27Mhz devices, since the logitech-hidpp
code needs to be able to differentiate them from other devices instantiated
by the logitech-dj code.

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.
