gpio: davinci: Add the missing of-node pointer

Keerthyj · linusw · commit 310a7e604351 · 2016-02-10T10:59:12.000+01:00
Currently the first parameter of irq_domain_add_legacy is NULL.
irq_find_host function returns NULL when we do not populate the of_node
and hence irq_of_parse_and_map call fails whenever we want to request a
gpio irq. This fixes the request_irq failures for gpio interrupts.
