Thomas Gleixner bf54da7d3a avr32/at32ap: Fix race in installing chained IRQ handler

Fix a race where a pending interrupt could be received and the handler
called before the handler's data has been setup, by converting to
irq_set_chained_handler_and_data().

Search and conversion was done with coccinelle:

expression E1, E2, E3;

-if (irq_set_chained_handler(E1, E3) != 0)

+irq_set_chained_handler_and_data(E1, E3, E2);
