soc/tegra: fuse: Add nvmem keepout list

Browse source

On Tegra186 and later, various FUSE offsets are restricted and cannot be
accessed from CCPLEX. Currently nvmem binary interface allows reading
such offsets from userspace, which results in RAS errors.

Add nvmem keepout lists to avoid any reads to restricted offsets.
