The STM32MP13x Device Part Number (also named RPN in reference manual)Applied on stm32-next.
only uses the first 12 bits in OTP4, all the other bit are reserved and
they can be different of zero; they must be masked in NVMEM result, so
the number of bits must be defined in the nvmem cell description.
