devices: add detect mechanism ...

We often encounter the situation where slow devices should not be
probed during startup since probing is slow and maybe unnecessary
for unused devices. With MMC we have the 'probe' device parameter,
for ata we have the same, for USB we have the 'usb' command. Overall
this is not very consistent.
With MMC there is the additional problem that the probe parameter
is attached to the logical device when we often have the information
which physical device we want to probe.
This patch adds a 'detect' callback for devices and adds a command
to detect devices and to list the devices which are actually detecable.

driver: Attach info callback to device, not to driver ...

Since the info is device specific and not driver specific, attach
the callback to the device. This makes it possible to have a info
callback for a device which does not have a driver attached.

Add initial pinctrl support ...

This is a massively stripped down pinctrl support. The upper API
consists of only of:

int pinctrl_select_state(struct device_d *dev, const char *state);

This is used to setup the pinmux for a device to a certain state.
This function normally does not need to be called manually. The
device core will setup the default state before probing a device.

The pinctrl core has the job of handling the devicetree. It parses
the pinctrl phandles for a device from devicetree, finds the correct
pinctrl device and calls its set_state callback with the pinctrl
setup device node.

The simplicity of this pinctrl framework comes from the fact that
we:

- Limit usage to devicetree only for now. For non devicetree use the
  old legacy SoC specific APIs still can be used.
- Do not parse the devicetree into internal data structures which
  are used by the drivers later. This adds the overhead that we
  may parse the devicetree multiple times for more dynamic setups,
  but on the other hand we do not need to parse devices from the
  devicetree we don't use in barebox
- Do not detect resource conflicts. Since the framework mainly is
  a devicetree parser this would be hard to implement. It should
  be easy for board maintainers to avoid resource conflicts though.

drivers/base: fix corrupt device tree ...

dev_add_child is a very unsafe function. If called multiple times
it allows setting the same device to different parents thus corrupting
the siblings list. This happens regularly since:

|    bus: add bus device
|
|    automatically add it as parent of any bus device if none already specified
|
|    we have now a nice output per bus

If for example a FATfs is mounted this nice output per bus often ends with:

This patch fixes this by adding a device to its parents children list in
register_device so that dev_add_child is no longer needed. This function
is removed from the tree. Now callers of register_device have to clearly
set the parent *before* registering a device.
