arm64: dts: rockchip: RK356x: Add OTP description.

[Andrey Leonchikov <andreil499@gmail.com>]

Add OTP mapping, can be used on future by drivers.
Contain a factory-programmed values for a various peripheral.
U-Boot already use "CPU-ID" OTP value ("otp_id" on this patch).
All values from original Rockchip sources tree on github.
