When setting a pin direction verify that the requested direction is

This requires pin configuration information to be supplied by SoC data.

Set pin configuration type to
- PINMUX_TYPE_NONE at initialization time and when disabling a function
or freeing a GPIO
- PINMUX_TYPE_FUNCTION when enabling a function
- PINMUX_TYPE_INPUT or PINMUX_TYPE_OUTPUT when setting the GPIO
direction
Verify that the type is PINMUX_TYPE_NONE when enabling a function or
requesting a GPIO and return -EBUSY if it isn't.

The existing PFC pinconf implementation, tied to the PFC-specific pin

pinconf types to implement bias (pull-up/down) setup. Other pin
configuration options can be implemented later if needed.

The purpose of the dry-run is to ensure that a pin about to be

This proves that the dry-run isn't essential. Remove it.
