USBHID: report descriptor fix for MacBook JIS keyboard
This patch fixes the problem, that Japanese MacBook doesn't recognize some keys
like '\'(yen, or backslash), '|'(pipe), and '_'(underscore).
It is due to that MacBook JIS keyboard (jp106) sends wrong report descriptor.
It saids "logical maximum = 0x65", so Keyboard.0089 is mapped to Key.Unknown,
while it should be accepted as Key.Yen.
