Log Message:
octgpio: OCTEON GPIO controller driver

Port of OpenBSD octgpio(4) (Visa Hankala) onto the NetBSD fdtbus
gpio controller API.

Deviations from the OpenBSD original, per the SDK CSR definitions:
CN63XX/CN68XX and CN38/52/56/58XX have 16 pins and no XBIT_CFG
registers.  The OUTPUT_SEL output mux is cleared only on CN70XX and
newer, where it exists.

Attach at pass 3 so consumers (octmmc cd-gpios) find the controller
registered.  Primary motivation is SD card-detect on boards with a
real MMC slot but could drive LEDs and other features later.
