ARM omap hsmmc: Fix register offset ...

The hsmmc module has a 0x100 offset in its register space. The real
register space size for the module is 4K, so when we register the
device with the size 4k, we have to account for the offset in the
driver, not in the resource allocation.

mci: Allow to specify device name ...

When multiple MMC/SD cards are present in the system we often
have to have persistent names to identify them during runtime.

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.
