usb: fix support for HID keyboard

Browse Source 
This fixes issues with several HID keyboards by implementing
get_unaligned_le16(), which obviously may also fix other not-yet-known
issues. Hint: I had to look out for suspicious lines like follows in the
verbose log.

  [init -> usb_drv] get_unaligned_le16 called, not implemented

Also, quirks for cherry keyboards are now applied.
