Add support for a ChromeOS EC proximity driver that exposes a "front" proximity sensor via the IIO subsystem. The EC decides when front proximity is near and sets an MKBP switch 'EC_MKBP_FRONT_PROXIMITY' to notify the kernel of proximity. Similarly, when proximity detects something far away it sets the switch bit to 0. For now this driver exposes a single sensor, but it could be expanded in the future via more MKBP bits if desired.

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.
