- Create cmhardwr.c for ARM, stub it out.

- Create cmhardwr.c for ARM, stub it out.
- Implement KiInitMachineDependent -- this is only useful for x86 and has nothing relevant to ARM, so we just return.
- Implement HalAllProcessorsStarted (again, a no-op) and HalQueryRealTimeClock (uses the RTC on the board -- uboot must set it up first).
- Make sure we get the right Sp during a system call (this is still broken though).
- We need to fix our system call handler next.
