backports: bump drivers dependency that require I2C bus classes

Drivers that depend on I2C bus segments behind multiplexers to
have a class require quite a bit of collateral changes that I
don't have time to address. For those interested in trying to backport
this see commit eee543e8. This bumps the drivers that depend on this
that we carry to require at least v3.7 when this collateral evolution
was introduced. One driver is affected, rtl2832 -- defined under
CONFIG_DVB_RTL2832.

    i2c-mux: Add support for device auto-detection

    Let I2C bus segments behind multiplexers have a class. This allows for
    device auto-detection on these segments. As long as parent segments
    don't share the same class, it should be fine.

    I implemented support in drivers i2c-mux-gpio and i2c-mux-pca954x. I
    left i2c-mux-pca9541 and i2c-mux-pinctrl alone for the moment as I
    don't know if this feature makes sense for the use cases of these
    drivers.
