genirq/debugfs: Add missing IRQCHIP_SUPPORTS_LEVEL_MSI debug
Debug is missing the IRQCHIP_SUPPORTS_LEVEL_MSI debug entry, making debugfs
slightly less useful.
Take this opportunity to also add a missing comment in the definition of
IRQCHIP_SUPPORTS_LEVEL_MSI.
Fixes: 6988e0e0d283 ("genirq/msi: Limit level-triggered MSI to platform devices")
