Link to documentation for different block device types

Browse source 
The number of block devices used in an Android device is too damn high
(insert meme here). Let's at least add some links to documentation to
help describe the partition layout expected on a typical Android device.

This builds on top of the work in making the bootloader information
accessible (b/28905584).

Test: only adding comments. Policy compiles.
