Take into account the size of the interrupt cell. It's determined

by the parent for interrupt resources. This corrects parsing of
the interrupts property.

With parsing of the property fixed, add all interrupts to the
resource list. Bump the max. number of interrupts from 5 to 6
as scc(4) attached to macio(4) has 6 interrupts (3 per channel).
