Make power_supply_show_enum_with_available() replace these spaces with '_' when showing the available text-values. After this the output for a battery which supports "Long Life" will be e.g.: Fast [Standard] Long_Life or: Fast Standard [Long_Life] Modify power_supply_store_property() to accept both the original text-value with space and the alternative value with the spaces replaced by '_'. This allows users to write the value with '_' after seeing this on reading the 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.
