Shawn Nematbakhsh f0b564b4a0 system: Add generic bbram read / write routines ...

Add generic routines to read or write a byte to battery-backed RAM, and
implement vbnvcontext get/set using these routines.

BUG=chrome-os-partner:62952
BRANCH=reef
TEST=On reef, with subsequent commit, run "cutoff" on the console,
reattach AC, and verify device successfully wakes. Also verify Rp is
dropped on console 'reboot' and F3 + power from RW.
