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

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.
