sched: properly disable the watchdog
...
I have no idea what the FUCK the Engineers at ARM were thinking when
they decided to disable EVERY SINGLE FUCKING CPU COMPONENT on system
reset, except the FUCKING WATCHDOG. But this change will prevent the
system from randomly firing a watchdog reset.

Finish serial init code

The first major hurdle has been overcome, though several more are
still awaiting me. Next up is IRQ handling.

Implement core serial routines

This is just a rough baseline for the higher-level
serial handling code and will probably change
within the next couple of commits.
