Thinking about Ron's comments we might want to keep the different table
types more seperated. 

Thus instead of having dev::devops::write_tables() would it be
preferable to have several hooks for 

 1) linuxbios table
 2) ACPI tables
 3) MP table
 4) pirq table

The more complete 1 and 2 become, the less 3 and 4 will be needed.
In a perfect world we could choose to stop calling 2-4 and not compile
them in. This is nicer if the table generation is more seperated.

Regarding non-x86 systems: We don't want 2-4 on those anyways since no
operating system _expects_ they are there. And we definitely don't want
to change that.
