[entropy] Raise USB baud rate to match application 'cc20rng'
Using different baud rates for the two otherwise compatible applications risk confusing users of both applications. An espeicially unlucky case is setting host side to 460800 while reading from a board set to 921600 -- the stream will look random while it's actually pretty bad. Raising 'entropy' rather than lowering 'cc20rng' is motivated by the fact that cc20rng saturates 460800 baud(*) with its ~75 kB/s output. (*) 460800 baud should be 57.6 kB/s or 51.2 kB/s, depending on whether or not the stop bit is counted towards the baud rate. I would suppose it is.
