power: supply: Add Apple Brick ID power supply type
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.
