[0/3] i2c: testunit: let it trigger SMBusAlerts

Message

Finally, after all the prerequisites, here is now the series to let the
testunit trigger SMBusAlerts. First two patches are preparations, third
one is the real thing.

The patches are based on i2c/for-next and have been tested on a Renesas
Lager board (R-Car H2) and a Renesas Falcon board (R-Car V3U).

Next and final step is to update/clarify DT bindings so GPIOs are
recognized as custom SMBALERT# pins. Code is all there already.

Looking forward to comments!
