Add functions for (de)activating consoles and for setting baudrate

[Sascha Hauer]

We have some console users like load[bxy] which fiddle with device
parameters to control console activation and baudrate settings. This
series introduces functions for doing this and makes use of them where
possible. The serial download stuff is untested as I have been unable
to get that to work with any of the three protocols and kermit or minicom
as terminal programs. If anyone has a hint how this works I'd be grateful.
