Log Message:
Ditch the `simulated' software interrupt in favour of
hardware-assisted soft interrupts on all boards.
(Note: VMEChip2-less 162/172 not yet tested)

This greatly simplifies the `rei' path and allows
interrupt nesting to be tracked somewhat more easily.

As a result we now have a working CLKF_INTR() macro
and can detect uvm_fault() being called from an interrupt
(although there may still be a very short race detecting
the latter; need to investigate further).
