This series contains nvmem framework changes prerequisite for further
development of my previous series[1] that aims at removal of the
platform data struct from at24 EEPROM driver.

First we remove unused APIs and the global cell list. We then switch
to using kref instead of manual user counting. Next we simplify the
provider unregistration by removing the return value from
nvmem_unregister().

Next three patches improve the framework by adding a notifier chain
for future use and fixing the issue with nvmem device names.

Finally we add support for cell definitions, cell lookups and make
DT systems resolve the nvmem cells during provider's registration.

Last patch just uses the SPDX license identifiers.

Tested both DT and non-DT use cases.
