[PATCH 0/6] introduce fwnode in the I2C subsystem

[Clément Léger]

In order to allow the I2C subsystem to be usable with fwnode, add
some functions to retrieve an i2c_adapter from a fwnode and use
these functions in both i2c mux and sfp. ACPI and device-tree are
handled to allow these modifications to work with both descriptions.

This series is a subset of the one that was first submitted as a larger
series to add swnode support [1]. In this one, it will be focused on
fwnode support only since it seems to have reach a consensus that
adding fwnode to subsystems makes sense.
