Prepending new definitions should be preferred to assignment, as it is
simpler and more conducive to defining new machine configurations that
reuse these configurations.

currently there is no way to override the default SERIAL_CONSOLE,
this variable needs to be set only if the developer didn't set it already from
another layer.

The latest raspberrypi3 puts its console on ttyS0 instead of ttyAMA0 (like all
the preceding boards). Therefore pull this definition out of the common
include file and add it separately for each MACHINE.
