Input: bcm5974 - recover from failed mode switch
Mode switches sent before control response are ignored. This results in
an unresponsive trackpad and "bcm5974: bad trackpad package, length: 8"
repeated in logs.
On receiving unknown 8-byte packets, assume that mode switch was ignored
and schedule an asynchronous mode reset. The reset will switch the
device to normal mode, wait, then switch back to wellspring mode.
