allwinner-i2c, adm1272: Use device_cold_reset() for software-triggered reset

Rather than directly calling the device's implementation of its 'hold'
reset phase, call device_cold_reset(). This means we don't have to
adjust this callsite when we add another argument to the function
signature for the hold and exit reset methods.
