This is OK because nothing is using the define today?

$ git grep SRST_CRYPTO
Documentation/devicetree/bindings/crypto/rockchip-crypto.txt:           resets = <&cru SRST_CRYPTO>;
arch/arm/boot/dts/rk3288.dtsi:          resets = <&cru SRST_CRYPTO>;

Uh oh. Just don't change it and think about something else when it
starts to feel inconsistent.
