Fixing interrupt mapping of EMAC for canyonlands

The previous stuff was odd .... but was it broken ?

It was done this way because the EMAC actually has more interrupts than
that which are routed to different UICs, and so doing a local map this
way allows to target multiple parents.

Well, in the canyonlands case, it appears that the interrupts went to
the same pic, so the simpler representation should be correct as
well.  However, there certainly are boards where they go to multiple
pics, so we need this interrupt-map trick.

Doesn't emac has something like 4 more interrupts that we simply haven't
been bothered wiring up (because we don't use them ?)

Cheers,
Ben.
