e160f7d430 dm: core: Replace of_offset with accessor 
At present devices use a simple integer offset to record the device tree
node associated with the device. In preparation for supporting a live
device tree, which uses a node pointer instead, refactor existing code to
access this field through an inline function.

c4876320db sandbox: usb: Allow dynamic emulated USB device descriptors 
We would like the serial number to come from the device tree node name of
the emulated device. This avoids them all having the same name. Adjust the
code to support this.

f4f715360c dm: usb: sandbox: Add an emulator for USB flash devices 
This emulator supports USB enumeration and allows a local file to be provided
as the contents of the emulated flash stick. U-Boot can then use the file as
it would a normal device, with all access passing through the usb_stor layer
and the USB stack.
