power: supply: bq24190: Fix BQ24296 Vbus regulator support

There are 2 issues with bq24296_set_otg_vbus():

1. When writing the OTG_CONFIG bit it uses POC_CHG_CONFIG_SHIFT which
   should be POC_OTG_CONFIG_SHIFT.

2. When turning the regulator off it never turns charging back on. Note
   this must be done through bq24190_charger_set_charge_type(), to ensure
   that the charge_type property value of none/trickle/fast is honored.

Resolve both issues to fix BQ24296 Vbus regulator support not working.
