drivers: nvmem: add atmel_sfc driver

This driver handles the secure fuse controller that is present on the
sama5d2 series. It allows to read a 544 bits user defined area of fuses.
Content is exposed through 17 32 bits registers. Rather than adding
complicated logic in atmel_sfc_read() for individual bytes, read all
the 16 registers at once (which are loaded at SoC startup from fuses)
and store them in an array convenient for copying from it to buffers.

drivers: nvmem: add API for nvmem controllers

Add a nvmem API to access nvmem cells using device-tree description. This
API allows to register nvmeme provider and obtain nvmem cells for consumer.
Much like other subsystem, this one relies on the generic dt_driver
mechanism.
