Enable the exynos-otp nvmem driver. The driver reads the product and chip IDs from the OTP register space and register the SoC info to the SoC interface. The driver can be extended to empower the controller become nvmem provider. The fuse block stores various system information (TMU, ASV, etc.) which can be accessed by client drivers.
