[PATCH RFC] dt-bindings: crypto: inside-secure,safexcel: make eip/mem IRQs optional

From: Rafał Miłecki <rafal at milecki.pl>

Binding for this cryptographic engine defined 6 interrupts since its
beginning. It seems however only 4 rings IRQs are really required for
operating this hardware. Linux driver doesn't use "eip" or "mem" IRQs
and it isn't clear if they are always available (MT7986 SoC binding
doesn't specify them).

This deals with:
arch/arm64/boot/dts/mediatek/mt7986a-bananapi-bpi-r3.dtb: crypto at 10320000: interrupts: [[0, 116, 4], [0, 117, 4], [0, 118, 4], [0, 119, 4]] is too short
        from schema $id: http://devicetree.org/schemas/crypto/inside-secure,safexcel.yaml#
arch/arm64/boot/dts/mediatek/mt7986a-bananapi-bpi-r3.dtb: crypto at 10320000: interrupt-names: ['ring0', 'ring1', 'ring2', 'ring3'] is too short
        from schema $id: http://devicetree.org/schemas/crypto/inside-secure,safexcel.yaml#
