Completely overhaul interrupt handling on sgi. Cpu state now only stores a
logical IPL level, and per-platform (IP27/IP30/IP32) code will from the
necessary hardware mask registers.
This allows the use of more than one interrupt mask register. Also, the
generic (platform independent) interrupt code shrinks a lot, and the actual
interrupt handler chains and masking information is now per-platform private
data.
Interrupt dispatching is generated from a template; more routines will be
added to the template to reduce platform-specific changes and share as much
code as possible.
Tested on IP27, IP30, IP32 and IP35.
