Subject: [PATCH 446/469] dt-bindings: nvmem: rockchip,otp: Add compatible for
 RK3588

Document the OTP memory found on Rockchip RK3588 SoC.

Since RK3588 uses different clocks & resets configurations than PX30 /
RK3308, provide the required changes in the binding to be able to handle
both variants.
