dt-bindings: fsl: scu: add ocotp binding

Browse Source 
NXP i.MX8QXP is an ARMv8 SoC with a Cortex-M4 core inside as
system controller(SCU), the ocotp controller is being controlled
by the SCU, so Linux need use RPC to SCU for ocotp handling. This
patch adds binding doc for i.MX8 SCU OCOTP driver.
