Previously this RTC was using the file system-based i2c interface in /dev. Since the RTC is initialized pretty early on during system init, we call open() before stdin/stdout/stderr have been opened. RTEMS assumes that stdin == 0, stdout == 1, etc., and fails when that isn't the case. In particular, when stdin != 0, RTEMS assumes that it wasn't configured with a console driver and skips opening stdout/stderr, leading to confusing issues with the standard I/O streams.
