Subject: [PATCH v2 2/5] dt-bindings: interrupt-controller: Add Renesas RZ/V2H(P) Interrupt Controller
Add DT bindings for the Renesas RZ/V2H(P) Interrupt Controller.
Also add macros for the NMI and IRQ0-15 interrupts which map the
SPI0-16 interrupts on the RZ/V2H(P) SoC so that they can be
used in the first cell of the interrupt specifiers.
For the second cell of the interrupt specifier, since NMI, IRQn
and TINTn support different types of interrupts between themselves,
add helper macros to make it easier for the user to work out what's
available.
