There's all eight power domains can be controlled by max8660. V1~V5 is
controlled by SYS_EN signal. V6 & V7 is controlled by I2C bus. V8 is
VCC_BBATT domain that should be always ON. So we can't shutdown all
power on Aspenite since V8 shoudl be always ON.

So the key is SYS_EN. In Aspenite board, one signal of GPIO expander
is named EXP2_SYS_DIS_N. If we put this signal to low, the SYS_EN
signal will do a negative transition.

Thanks Haojian, Eric, Marek. That was useful info.
