Define enum inside the honeywell,transfer-function property block.
Set the correct irq edge in the example block.
Based on the datasheet, in table 13 on page 11:
"End-of-conversion indicator: This pin is set high when a measurement
and calculation have been completed and the data is ready to be
clocked out"
Add description on End-of-conversion interrupt.
