Thomas Gleixner 51b971b1b9 sh/intc: 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)
