Add support to thinkpad_acpi for returning the status of the palm sensor. This patch builds on the work done previously for the input device implementation (which was not needed). Both lap and palm sensor are using sysfs and they are combined into the proxsensor block. Note: On some platforms, because of an issue in the HW implementation, the palm sensor presence may be incorrectly advertised as always enabled even if a palm sensor is not present. The palm sensor is intended for WWAN transmission power control and should be available and correct on all WWAN enabled systems. It is not recommended to use this interface for other use cases.

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.
