nvmem: layouts: add U-Boot env layout
U-Boot environment variables are stored in a specific format. Actual
data can be placed in various storage sources (MTD, UBI volume, EEPROM,
NVRAM, etc.).
Move all generic (NVMEM device independent) code from NVMEM device
driver to an NVMEM layout driver. Then add a simple NVMEM layout code on
top of it.
This allows using NVMEM layout for parsing U-Boot env data stored in any
kind of NVMEM device.
The old NVMEM glue driver stays in place for handling bindings in the
MTD context. To avoid code duplication it uses exported layout parsing
function. Please note that handling MTD & NVMEM layout bindings may be
refactored in the future.

nvmem: layouts: onie-tlv: Add new layout driver
This layout applies on top of any non volatile storage device containing
an ONIE table factory flashed. This table follows the tlv
(type-length-value) organization described in the link below. We cannot
afford using regular parsers because the content of these tables is
manufacturer specific and must be dynamically discovered.

nvmem: layouts: sl28vpd: Add new layout driver
This layout applies to the VPD of the Kontron sl28 boards. The VPD only
contains a base MAC address. Therefore, we have to add an individual
offset to it. This is done by taking the second argument of the nvmem
phandle into account. Also this let us checking the VPD version and the
checksum.

nvmem: core: introduce NVMEM layouts
NVMEM layouts are used to generate NVMEM cells during runtime. Think of
an EEPROM with a well-defined conent. For now, the content can be
described by a device tree or a board file. But this only works if the
offsets and lengths are static and don't change. One could also argue
that putting the layout of the EEPROM in the device tree is the wrong
place. Instead, the device tree should just have a specific compatible
string.
Right now there are two use cases:
(1) The NVMEM cell needs special processing. E.g. if it only specifies
a base MAC address offset and you need to add an offset, or it
needs to parse a MAC from ASCII format or some proprietary format.
(Post processing of cells is added in a later commit).
(2) u-boot environment parsing. The cells don't have a particular
offset but it needs parsing the content to determine the offsets
and length.
