Looking at this further, there's already a tegra_init_fuse() call made
from tegra_init_early(), so rather than adding a second init function
into the fuse code, I'd rather just augment that function, unless
there's some reason add_device_randomness() won't work at that time?
If that will work, I'll supply an alternate patch that replaces this,
since I also want to remove the tegra_chip_uid() function, and need to
make the add_device_randomness() call not use tegra_chip_uid() on
Tegra30 or later, since the set of fuses for the chip ID changed radically.
