U-Boot stores its setup as environment variables. It's a list of
key-value pairs stored on flash device with a custom header.

This commit adds an NVMEM driver that:
1. Provides NVMEM access to environment vars binary data
2. Extracts variables as NVMEM cells

It can be used for:
1. Accessing env variables from user-space
2. Reading NVMEM cells by Linux drivers

Applied to https://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux.git mtd/next, thanks.

Hi Miquel,

Any reason why this nvmem driver is taken via mtd tree?

This is going to conflict with other nvmem patches that are touching KConfig and Makefile
