firmware: raspberrypi: print time using time64_t
The firmware timestamp is an unsigned 32-bit value, but we copy it into a signed 32-bit variable, so we can theoretically get an overflow in the calculation when the timestamp is between 2038 and 2106. This changes the temporary variable to time64_t and changes the deprecated time_to_tm() over to time64_to_tm() accordingly. There is still an overflow in y2106, but that is a limitation of the firmware interface, not a kernel problem.
