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.

The SNVS LPGR IP block is also found on other i.MX SoCs that
are not covered by the current SOC_IMX6 || SOC_IMX7D logic.
One example is the i.MX7ULP.
To avoid keep expanding the SoC logic selection, make it broader
by using the more generic ARCH_MXC symbol instead.

The Allwinner SoCs have an efuse supported in Linux, with a matching Device

Now that we have the DT validation in place, let's convert the device tree
bindings for that controller over to a YAML schemas.
