pit: Rename pit to peach_pit.

The name pit goes by in many places in chromeos is peach_pit, where peach is
the base name and pit is the name of this particular variant. To make it
easier to work with within chromeos and to make the board names a little less
ambiguous, this change renames the pit board to peach_pit, and from Pit to
Peach Pit.
