ryu: export board version

Browse Source 
Export the board version through the usual EC_CMD_GET_BOARD_VERSION.
Add an option to use the board-specific board_get_version() callback
rather than doing the generic GPIO binary decoding since here the
version is ternary encoded.

Signed-off-by: Vincent Palatin <vpalatin@chromium.org>

BRANCH=smaug
BUG=none
TEST=execute 'ectool boardversion' on the AP and see the right number.
