This allows fw_devlink to create device links between consumers of an

This patch landed some time ago in linux-next as commit 4104ca776ba3 
("of: property: Add fw_devlink support for interrupts"). It breaks MMC 
host controller operation on ARM Juno R1 board (the mmci@50000 device 
defined in arch/arm64/boot/dts/arm/juno-motherboard.dtsi). I didn't 
check further what's wrong there as without MMC mounting rootfs fails in 
my test system.
