Subject: [PATCH] cdba: add per-board power key press duration

On some Alpaca boards the power key needs to be pressed for longer than
the default duration, otherwise the board powers down automatically.

Add a 'power_key_press_ms' board configuration property to allow
specifying the duration in milliseconds.
