nvmem: add nvmem_regmap_register helper
Registering a nvmem device for a regmap involves some boilerplate that
doesn't need to change from driver to driver:
- Reads are made aligned, to support normal use with md
- Writes are passed along as is
- nvmem parameters can be extracted from regmap
Instead of having to replicate this driver by driver, add one helper to
make this adaptation easier.
