Replace the GPIO-based SDHI and MMCIF pinmux configuration by pinctrl
mappings.

Board code used the non-pulled-up version of the function GPIOs, but
those are defined in the PFC driver as enabling the pull-ups anyway.
Enable pull-ups on the MMCIF data and command pins through the pinconf
API.

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
types, isn't used by drivers or boards. Replace it with the generic
pinconf types to implement bias (pull-up/down) setup. Other pin
configuration options can be implemented later if needed.
