irqdomain sets up hwirq for you. Don't set it manually because it will
mess up irqdomain mappings.

Ditto here; irqdomain manages the domain pointer internally.

Again; this is overstepping onto irqdomain responsibility. Don't set
up the irq in the xlate routine; only parse the date and if you need to
store extra data like 'set_edge_handler' (using the hwirq number as the
key). The irq setup must be done in the .map callback which will be
passed the actual irq number to be used.
