add more mosys platform information to chrome://system

To be able to debug various hardware related issues on Spring, we need
to know precisely the board revision inside the machine.
"mosys platform version" is returning a decoded form of the board revision
id and various other "mosys platform" subcommands give hw specific info.
Let's add these to chrome://system and feedback reports.

BUG=chrome-os-partner:21674
TEST=on Spring, open chrome://system and see the board revision properly
reported under "platform_info", fill a feedback and also see it in the
feedback "Product Specific Data"
