- HDAMA boots!

- Set the bootstrap processor flag in the mptable.
- Implement 64bit support in our print statements
- Fix the reporting of how many cpus we are waiting to stop.
  It is the 1 less than the actual number of cpus running.
- Actually enable cpu_initialization.
- Fix firstsiblingdevice in config.g
- Add IORESOURCE_FIXED to all of the resources set by config.g
- Fix the apic_cluster rule to add an apic_cluster path not an apic path.
- Add a div64.h to assist in the 64bit printf.

* do_div() is NOT a C function. It wants to return

*
* - modifies the 64-bit dividend _in_place_
* - returns the 32-bit remainder
*
* This ends up being the most efficient "calling
* convention" on x86.
