power: fg-util: Notify FCC and FV to charger only if they're valid 



Float voltage (FV) and Fast charging current (FCC) for a battery
is specified under the battery profile device tree. This is read
by the FG driver and notified to the charger driver. If these
parameters are not specified, then they're initialized to -EINVAL
currently. Do not notify these negative numbers to charger driver
which can affect charging parameters.
