Subject: hid: handle Switch 2 commands 213 and 220

213 (32 bytes and the aruid, no reply data) is sent per controller every
frame by Kirby Air Riders; through the auto stub it logged two lines per
call. 220 (16 bytes and the aruid) replies with one byte, which the auto
stub left to the message buffer's leftovers. Accept 213 quietly and answer
220 with zero.
