When the VBATSENSE<2.2V, AXP288 judge it as battery is not present. When VBATSENSE goes higher than 2.2V, it
indicates battery present or is inserted. For the case of battery insertion or removal, IRQ will be asserted. Battery presence
status is indicated in REG01H[5]and the battery detection function can be set by REG 32H[6]. When charger insert, AXP288
will send a pulse to detect battery is present or not per 16 seconds.
