gpio: remove gpiobus_attach_bus

2025-08-13T11:14:00+00:00

Since gpiobus_attach_bus can attach the gpiobus child along with its
children in the same bus pass, the parent controller's reference to
gpiobus might not be set by the time the children need it. Instead,
drivers should use gpiobus_add_bus and explicitly call
bus_attach_children.

Add the GPIO driver for the ADI Engineering RCC-VE and RCC-DFF/DFFv2.

This driver allows read the software reset switch state and control the
status LEDs.

The GPIO pins have their direction (input/output) locked down to prevent
possible short circuits.

Note that most people get a reset button that is a hardware reset.  The
software reset button is available on boards from Netgate.
