bq2589x: update driver

Browse Source 
Update the BQ2589x charger driver to configure properly the boost
used as a VBUS 5V source.
Define the bits used for I2C registers configuration.
Return success in unused charger callbacks to avoid blocking the
charge state machine.

BUG=chrome-os-partner:38603
TEST=On Ryu P4 reworked with BQ25892, plug a C-A receptacle adapter and
see the 5V VBUS coming up, un-plug it and see VBUS going away,
try several PD/type-C charger and check the selected current limit.
