Now that nvmem has gained support for defining cells from board files and
looking them up from relevant drivers[1], it's time for a respin of the
previous series[2] that aims at removing struct at24_platform_data from
the tree.

Since I took over maintainership of the at24 driver I've been working
towards removing at24_platform_data in favor for device properties.

DaVinci is the only platform that's still using it - all other users
have already been converted.

One of the obstacles in case of DaVinci is removing the setup() callback
from the pdata struct, the only user of which are some davinci boards.

First we add support for nvmem to MTD in a way previously discussed with
Boris Brezillon and Srinivas Kandagatla.

Then, since most boards use the EEPROM to store the MAC address, we register
relevant cells for all users, implement a function that allows to read
the MAC address from nvmem (and also replaces the previous DT-specific
variant) and make davinci_emac aware of it.

Next we switch all davinci users to using at24 device properties instead
of platform data. While we're at it: we remove all other traces of the
setup callback and platform data from davinci.

Finally we remove the at24 platform data structure.

I kept the review tags in patches that haven't changed from the last
submission.

As far as merging of this series goes: I'd like to avoid dragging it over
four releases. The series is logically split into five groups:

patches 1-2: nvmem and mtd changes
patches 3-9: davinci arch-specific changes
patches 10-13: networking changes
patches 14-24: davinci specific again
patch 25: final at24 change

With that I believe we can do the following: Greg KH could pick up the
first two patches into his char-misc tree. Sekhar would take the second
group and the third would go through the networking tree since the first
three sets are not linked in any way. This would be merged for 4.21. Then
for the next release Sekhar would pick up 14-24, provide an immutable
branch for me and I'd merge the final patch for at24 and send it upstream
through Wolfram's i2c tree (maybe we could even delay the i2c PR in the
merge window to avoid the immutable branch altogether).
