power: supply: Change usb_types from an array into a bitmask

The bit_types array just hold a list of valid enum power_supply_usb_type
values which map to 0 - 9. This can easily be represented as a bitmap.

This reduces the size of struct power_supply_desc and further reduces
the data section size by drivers no longer needing to store the array.

This also unifies how usb_types are handled with charge_behaviours,
which allows power_supply_show_usb_type() to be removed.
