sh-pfc: Return an error if a pin doesn't support the requested direction

When setting a pin direction verify that the requested direction is
supported, and return an error if it isn't.

This requires pin configuration information to be supplied by SoC data.
The check is a no-op if the information is not supplied.

sh-pfc: Clean up pin configuration type handling

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.

sh-pfc: Remove configuration dry-run and free

The purpose of the dry-run is to ensure that a pin about to be
configured isn't in use. However, the current implementation is a no-op.
This proves that the dry-run isn't essential. Remove it.

Freeing configuration then becomes a no-op as well. Remove it.
