[PATCH 0/3] nvmem: add ONIE NVMEM cells provider

[Vadym Kochan]

This series adds cells parser for the ONIE TLV attributes which are
stored on NVMEM device. It adds possibility to read the mac address (and
other info) by other drivers.

Because ONIE stores info in TLV format it should be parsed first and
then register the cells. Current NVMEM API allows to register cell
table with known cell's offset which is not guaranteed in case of TLV.

To make it properly handled the NVMEM parser object is introduced. The
parser needs to be registered before target NVMEM device is registered.
During the registration of NVMEM device the parser is called to parse
the device's cells and reister the cell table.
