gpio: omap: Add devicetree probe support ...

This adds devicetree probe support for the OMAP gpio ports and
also makes sure the corresponding platform_devices don't get
registered when they are already present from devicetree.

pinctrl: Add functions to select pinctrl from device_node ...

Instead of requiring a device pointer, add a functions to select
the pinctrl state based on a device node.
The AM33xx cpsw devicetree description has several subdevices with
pinctrl information attached to them. In barebox we do not handle
the subdevices as distinct devices, so the pinctrl is never configured
correctly and the mdio bus subdevice stops working. This patch makes
it possible to configure the pinctrl without having a device.

spi: omap: encode register offset into device_id ...

The omap3 and omap4/am33xx spi cores differ in the offset of the
registers in the address space. Instead of encoding this into the
resources use the platform_device_id mechanism. This is done in
preparation for devicetree probe support where the address space
is in the devicetree and can't be adjusted.

gpiolib: import gpio_request_array() from linux 3.7 ...

Also import related functions gpio_request_one() and
gpio_free_array().

This commit imports code from linux 3.7 as
the more recent linux kernel versions use gpiolib descriptors,

      gpiolib: use descriptors internally

      Make sure gpiolib works internally with descriptors and (chip, offset)
      pairs instead of using the global integer namespace. This prepares the
      ground for the removal of the global gpio_desc[] array and the
      introduction of the descriptor-based GPIO API.

mci: mxs: support overwriting the device name via platform data ...

The current implementation of the bootloader specification depends on the
hardware name and the name of the device in /dev to match. As the default
hardware name is mciX and the device name is diskY the bootloader spec
cannot be used as is.

This patch implements a way to overwrite the device name similar to what is
possible for the imx-esdhc driver.
