On DRA7 compatible IRQ crossbar, IRQ 10 default mapped to L3_APP_IRQ,
IRQ133 is default mapped to NMI pin, 139 and 140 crossbars are
unused(not routed). Mark these as unused crossbar IRQs.

Technical Reference Manual documentation update expected
DRA72x-TRMINC00067 is being used to track the update.

Ok, if dts would be the better approach then I can change this.
