Some devices with a goodix touchscreen have more then 1 capacitive touch-key. This commit replaces the current support for a single touch-key, which ignored the reported key-code. With support for up to 7 touch-keys, based upon checking the key-code which is post-fixed to any reported touch-data. KEY_LEFTMETA is assigned to the first touch-key (it will still be the default keycode for devices with a single touch-key). KEY_F1, KEY_F2... are assigned as default keycode for the other touch-keys. This commit also add supports for keycode remapping, so that systemd-udev's hwdb can be used to remap the codes to send keycodes to match the icons on the buttons for devices with more then 1 touch-key.

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.
