The armada-370-xp irqchip fails in some randconfig builds because
of a missing declaration:
In file included from drivers/irqchip/irq-armada-370-xp.c:23:
include/linux/irqchip/irq-msi-lib.h:25:39: error: 'struct msi_domain_info' declared inside parameter list will not be visible outside of this definition or declaration [-Werror]
Add a forward declaration for the msi_domain_info structure.
[ tglx: Fixed up the subsystem prefix. Is it really that hard to get right? ]
Fixes: e51b27438a ("irqchip: Make irq-msi-lib.h globally available")

Move irq-msi-lib.h into include/linux/irqchip, making it available
to compilation units outside of drivers/irqchip.
This requires some churn in drivers to fetch it from the new location,
generated using this script:
git grep -l -w \"irq-msi-lib.h\" | \
xargs sed -i -e 's:"irq-msi-lib.h":\<linux/irqchip/irq-msi-lib.h\>:'
