power_supply: Fix regression for 'type' property
Commit 5f487cd34f4337f9bc27ca19da72a39d1b0a0ab4 (power_supply: Use
attribute groups) causes a regression the power supply core does not
export the 'type' attribute anymore.
POWER_SUPPLY_PROP_TYPE is handled by the power supply core without the
low-level driver, so power_supply_attr_is_visible() must always return
the entry as readable.
