to avoid spamming that sbpd thread with unrelated issues.

Trying to use gpio-shutdown with GPIO3, so that a single button can halt
the system or wake-from-halt.

With the following settings the shutdown works occasionally - the
wake-up always works.

Another user, meq123, reported success using a different pin for the
shutdown.  Possible reasons for the difference are that I2C uses GPIO3,
and GPIO3 has a hardwired (1k8) pull-up resistor.
