The hsmmc module has a 0x100 offset in its register space. The real

driver, not in the resource allocation.

For proper USB function the usbmisc registers have to be initialized.
This patch adds a driver which matches for the usbmisc registers. This

driver and an ULPI transceiver if necessary. Currently only host mode
is supported, but device support can be added later.

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.
