This patchset introduces a new driver subsystem, meant to support eFuse
(alias OTP, one-time-programmable) devices.

The motivation behind this work is to have a common place for drivers
that are currently more or less scattered: the tegra efuses are in
drivers/soc/ and the sunxi efuses in drivers/misc/eeprom.

For now, there's no proposal for a generic efuse API. Instead, we simply
group the drivers together.

This patchset is the result of the initial submission for IMG Pistachio
eFuse support [1]. Our first proposal was to follow the Tegra efuse, and
put the Pistachio efuse in drivers/soc. After some discussion we finally
agreed [2] to first create an efuse directoy, and then put all efuse drivers
in it.

As always, all comments are welcome!

Have you looked at the EEPROM framework currently in discussions? The
two seems to be covering pretty much the same use cases.

Nope, I was obviously unaware of that. Guess we'll wait until the
discussion is settled and use that framework.

Thanks!
