This fixes the TODO to parse strings and convert them to enum values
when writing to a power_supply class property sysfs attribute.
There is at least one driver that has a writable enum property that
previously could only be written as an integer, so a fallback to writing
enums as integers instead of strings is provided so we don't break existing
userspace programs.

Apple currently supports three very common USB chargers:
https://www.apple.com/power-adapters/
These chargers implement a proprietary Apple method for advertising
1A, 2.1A, and 2.4A at 5V called "Brick ID".
In addition, 3rd parties implement the same charging method in many
charging accessories that work with iOS devices.
Devices that have charger detection chips such as the Pericom PI3USB9281,
eg. Google Chromebook Pixel 2015, are capable of detecting
these chargers, so let's add a type to facilicate passing that info
up to userspace.
This adds a separate power supply type for Apple's proprietary
"Brick ID" charging method.

This moves all power supply drivers from drivers/power/
to drivers/power/supply/. The intention is a cleaner
source tree, since drivers/power/ also contains frameworks
unrelated to power supply, like adaptive voltage scaling.
