This will be used to implement non-blocking keyboard polling in case of
errors.

(cherry picked from commit 3437121c037f502a3b0faaec97059777034a1ead)
Current emulator select logic in usb_emul_find_devnum() is to test
the USB address. The USB address of the device being enumerated is
initialized to zero at the beginning of the enumeration process in
usb_setup_device(). At this point, the saved USB address in the
platform data has not been assigned to any valid USB address either.
This means: the logic will select an emulator device according to
its sequence of declaring order in the device tree. Take test.dts
for example, flash-stick@0 will be selected before flash-stick@1.
But unfortunately such logic is wrong.
In fact USB devices show up in a random order during the enumeration
which means usb_emul_find_devnum() may be called on port 3 for keyb@3
before on port 0 for flash-stick@0.
To fix this, we introduce a new emulator uclass specific platdata
to store the USB device's port number on its parent hub, and update
the logic to test the port number instead.

With the root hub unbinding in usb_stop(), there is no need to do
a Sandbox-specific reset operation. usb_emul_reset() is no longer
used anywhere, drop it.

This can be useful outside of the sandbox usb emulation uclass
driver. Expose it as a public API with a proper prefix (usb_emul_).

Quite a few places have a bind() method which just calls dm_scan_fdt_dev().
We may as well call dm_scan_fdt_dev() directly. Update the code to do this.

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.

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.
