The Gumstix Overo is a computer on module using an OMAP3 processor.
This module must be plugged into an expansion board.

This patch adds a first device tree support for the Overo, using the
Tobi expansion board. The current support is able to boot and mount
the rootfs from MMC.

This patche also updates the omap3 dtb build target.

Currently working:
- mmc0 (on board microSD)
- i2c0 and i2c2 (i2c1 not used)
- led on GPIO

The device/node resources (like, IORESOURCE_MEM and IORESOURCE_IRQ)
are overwritten by hwmod resources, due to all known reasons but
that should not be the reason for not providing all the information
in the DTS blob. Ideally we should use DTS resource and use HWMOD
framework wherever required and for only specific things.

Newer platforms like, OMAP5 and AM33XX, we only support DT boot mode,
so this patch is preparation for the future where we supposed to get
rid of hwmod dependency anyway.

With the new devices (like, AM33XX and OMAP5) we now only support
DT boot mode of operation and now it is the time to start killing
slowly the dependency on hwmod, so with this patch, we are starting
with device resources.
The idea here is implemented considering to both boot modes -
  - DT boot mode
    OF framework will construct the resource structure (currently
    does for MEM & IRQ resource) and we should respect/use these
    resources, killing hwmod dependency.
    If pdev->num_resources > 0, we assume that MEM & IRQ resources
    have been allocated by OF layer already (through DTB).

    Once DMA resource is available from OF layer, we should
    kill filling any resources from hwmod.

  - Non-DT boot mode
    Here, pdev->num_resources = 0, and we should get all the
    resources from hwmod (following existing steps)

When booted with some resource will have their name set to NULL. This can
cause later kernel crash since this is not expected by the platform code.

When we boot without DT the devices are created with platform_device_add()
which itself fixes up the missing resource names:
if (r->name == NULL)
	r->name = dev_name(&pdev->dev);

The of core also fixes up the resource names when taking the information
from DT data - in __of_address_to_resource():
r->name = name ? name : dev->full_name;

When we boot OMAP with devicetree: of will create the devices based on the
DT data so the resource names are guarantied to be not NULL. Since we have
the 'ti,hwmod' tag, we remove the of created resources from the device and
re-create them based on hwmod data. If the hwmod data does not specify a
name for a resource it will be NULL.
This can cause kernel crash if the driver uses
platform_get_resource_byname() to get any resource.
