Make sure to also restore the register base address on sysfs
registration failure.

From: Thierry Reding <treding@nvidia•com>
The nvmem framework provides a generic infrastructure and API to access
the type of information stored in fuses such as the Tegra FUSE block.
Implement an nvmem device that can be used to access the information in
a more generic way to decouple consumers from the custom Tegra API and
to add a more formal way of creating the dependency between the FUSE
device and the consumers.

Typically nvmem cells would be stored in device tree. However, for
compatibility with device trees that don't contain nvmem cell
definitions, register lookups for cells currently used by consumers.
This allows the consumers to use the same API to query cells from the
device tree or using the legacy mechanism.

Instead of using the custom Tegra FUSE API to read the calibration fuse
for the clock on GM20B, use the nvmem API. This makes the dependency
between the two devices more explicit and decouples the driver from one
another.
