Looks good! I did some measurements against power meter and chip seems
to be low power state by default. After firmware is downloaded and chip
is put to sleep, it does not answer that fw status check, until it is
woken up. There should not be ~any I/O during I2C probe(), so removing
that quite useless check is OK.
