Introduce a new HID quirk to indicate that this device has to be enabled after the panel's backlight is enabled, and update the driver data for the elan devices to enable this quirk. This cannot be a I2C HID quirk because the kernel needs to acknowledge this before powering up the device and read the VID/PID. When this quirk is enabled, register .panel_enabled()/.panel_disabling() instead for the panel follower. Also rename the *panel_prepare* functions into *panel_follower* because they could be called in other situations now.

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 reStructuredText 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.
