Subject: [PATCH 05/38] dt-bindings: crypto: inside-secure,safexcel: Mandate only ring IRQs

Not all IP implementations of EIP97 and EIP197 have the EIP and
MEM interrupts hooked up to the SoC, and those are not required
for functionality as status for both can be polled (and anyway
there's even no real need to poll, but that's another story).

As an example of this, the MediaTek MT7968A and MT7986B SoCs do
not have those two interrupts hooked up to their irq controlller.

For this reason, make the EIP and MEM interrupt optional.
