In order to turn the Tonberry device on more reliably even if the power button is only pressed for a short time, move the setting of POWER_EN pin to high from the python board_init to the MICROPY_BOARD_STARTUP macro so that is is started in the C startup code run before the micropython interpreter is initialized. Measured time from power on to POWER_EN time was 600-800 ms with the python board_init, vs. 155 ms for the MICROPY_BOARD_STARTUP. Signed-off-by: Matthias Blankertz <matthias@blankertz.org>
