Adam Thomson f2a8aa053c typec: tcpm: Represent source supply through power_supply
This commit adds a power_supply class instance to represent a
PD source's voltage and current properties. This provides an
interface for reading these properties from user-space or other
drivers.

For PPS enabled Sources, this also provides write access to set
the current and voltage and allows for swapping between standard
PDO and PPS APDO.

As this represents a superset of the information provided in the
fusb302 driver, the power_supply instance in that code is removed
as part of this change, so reverting the commit titled
'typec: tcpm: Represent source supply through power_supply class'

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
