U-Boot environment variables can be stored in various data sources. MTD is just one of available options. Refactor DT binding into a layout so it can be used with UBI volumes and other NVMEM devices.

Most NVMEM layouts are static and thus do not require additional description
|
|
besides the bytes/bits offset and length. Other layouts can be less statically
|
|
define and might require dynamic reading of the NVMEM device in order to
|
|
perform their parsing. The nvmem-layout container is here to describe these.
