cleanup: Re-enable keyboard console channel for ARM boards

Originally, the ARM boards printed the keyboard scan matrix whenever
it changed.  This generated a lot of output, so we filtered that at
the console channel level.  When we refactored the keyboard scan
module, that changed so that the scan matrix was not printed by
default, and the 'ksstate' debug command was used to enable printing
it.  But on ARM boards, 'ksstate on' wouldn't do anything without ALSO
using 'chan -1' to turn the keyboard console channel back on.  And
without the scan matrix printing by default, there's no reason to keep
the keyboard channel off by default.
