dt-bindings: nvmem: stm32: new property for data access
Introduce boolean property st,non-secure-otp for OTP data located
in a factory programmed area that only secure firmware can access
by default and that shall be reachable from the non-secure world.
This change also allows additional properties for NVMEM nodes that
were forbidden prior this change.
