This change is required for NVMEM consumers to get expected MAC address
from U-Boot env data variable "ethaddr".

To address some previous concerns:
1. Yes, U-Boot env binding & driver should be converted to NVMEM layout
2. My priority is to get working MAC rather than fancy DT syntax
3. I AM going to convert U-Boot env into layout later
4. This work DOESN'T conflict with layout migration
5. This code WILL stay during / after layout migration

My brain limitations don't allow me to handle everything at once, please
let's review what I already have here.

Rafał Miłecki (3):
  dt-bindings: nvmem: u-boot,env: add MAC's #nvmem-cell-cells
  nvmem: core: support specifying both: cell raw data & post read
    lengths
  nvmem: u-boot-env: post-process "ethaddr" env variable
