Since commit 935df1bd40d4 ("of/irq: Factor out parsing of interrupt-map parent
phandle+args from of_irq_parse_raw()"), An interrupt tree without
an interrupt-map is not updated to the parent interrupt and it causes the irq
domain not to be found in some out-of-tree device-tree.
Fixes: 935df1bd40d4 ("of/irq: Factor out parsing of interrupt-map parent phandle+args from of_irq_parse_raw()")
