Export
of_get_mac_addr_nvmem()
and rename it to
of_get_mac_address_nvmem()
in order to fit the convention followed by the existing exported helpers
of the same kind.
This way, OF compatible drivers using eg. fwnode_get_mac_address() can
do a direct call to it instead of calling of_get_mac_address() just for
the nvmem step, avoiding to repeat an expensive DT lookup which has
already been done once.
Eventually, fwnode_get_mac_address() should probably be updated to
perform the nvmem lookup directly, but as of today, nvmem cells seem not
to be supported by ACPI yet which would defeat this kind of extension.

This reverts commit 9ed319e411915e882bb4ed99be3ae78667a70022.
We can already post process a nvmem cell value in a particular driver.
Instead of having yet another place to convert the values, the post
processing hook of the nvmem provider should be used in this case.

Some NVMEM devices have text based cells. In such cases MAC is stored in
a XX:XX:XX:XX:XX:XX format. Use mac_pton() to parse such data and
support those NVMEM cells. This is required to support e.g. a very
popular U-Boot and its environment variables.

Commit 406f42fa0d3c ("net-next: When a bond have a massive amount
of VLANs...") introduced a rbtree for faster Ethernet address look
up. To maintain netdev->dev_addr in this tree we need to make all
the writes to it got through appropriate helpers.
There are roughly 40 places where netdev->dev_addr is passed
as the destination to a of_get_mac_address() call. Add a helper
which takes a dev pointer instead, so it can call an appropriate
helper.
Note that of_get_mac_address() already assumes the address is
6 bytes long (ETH_ALEN) so use eth_hw_addr_set().

Rob suggests to move of_net.c from under drivers/of/ somewhere
to the networking code.
