From: "Song, Hongyan" <hongyan.song@xxxxxxxxx>
The maximum globale report size has changed from 32->...->96->128 in
the past years.
With the development usage of HID, the report_size max value 128 cannot
satisfy all requirements. There is a need which report size is 192,
while max size 128 blocked it as illegal length, so increase the
report size to satisfy it and more demands in the future.
