d8a26f0300 usb: sandbox: Add a USB emulation driver
Add a simple USB keyboard driver for sandbox. It provides a function to
'load' it with input data, which it will then stream through to the normal
U-Boot input subsystem. When the input data is exhausted, the keyboard stops
providing data.

af9c7c11e9 sandbox: usb: Allow finding a USB emulator for a device
Each USB device has an emulator. Currently this can only be found by
supplying the 'pipe' value, which contains the device number. Add a way
to find it directly from the emulated device.

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.

5db439920b dm: usb: sandbox: Add an emulator for USB hub emulation
All USB controllers need a root hub. Add a sandbox emulation for this so
that we can add USB devices to sandbox.

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.

019808f97c dm: usb: sandbox: Add a uclass for USB device emulation
With sandbox we want to be able to emulate USB devices so that we can test
the USB stack. Add a uclass to support this. It implements the same
operations as a normal USB device driver, but in this case passes them on
to an emulation driver.
