Andrew Chant 169742e2db usblib: usb_device_get_string decoding fixes.
usb_device_get_string converts incoming ucs-2 text
to ascii by truncating the upper byte of each
character.  This is error prone.

This patch introduces usb_device_get_string_ucs2
to access raw USB string descriptors, as well as
changes usb_device_get_string to replace any non
ascii character with '?'.
