power: supply: bq24190_charger: Add support for "charge_types" property

Browse Source 
The bq24190 power_supply class device has a writeable "charge_type"
property, add support for the new "charge_types" property. Reading this
returns a list of supported charge-types with the currently active type
surrounded by square brackets, allowing userspace to find out which
enum power_supply_charge_type values are supported.

This has been tested on a GPD win gaming-handheld.
