power: supply: bq24190_charger: Fix bq24190_vbus_is_enabled() wrong false return

The datasheet says that the BQ24190_REG_POC_CHG_CONFIG bits can
have a value of either 10(0x2) or 11(0x3) for OTG (5V boost regulator)
mode.

Sofar bq24190_vbus_is_enabled() was only checking for 10 but some BIOS-es
uses 11 when enabling the regulator at boot.

Make bq24190_vbus_is_enabled() also check for 11 so that it does not
wrongly returns false when the bits are set to 11.
