[Asterisk-doc] Hardware IRQ

[Leif Madsen]

Actually, this is exactly the kind of thing we are looking for.  This is a
very good start to the IRQ sharing issues!  Thanks!

I will see what I can do about re-wording a couple of sections which aren't
as full as they need to be (I understand this was done quickly).

Keep up the good work!
Leif Madsen.
