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.
