power: supply: bq2415x_charger: report online status

Browse Source 
Provide the Online property. This chip does not have specific flags to
indicate the presence of an input voltage, but this is implied by all valid
charging states. Fault states also only occur when VBUS is present, so set
Online true for those as well.
