sandbox: i2c: Support i2c emulation with of-platdata
At present the i2c emulators require access to the devicetree, which is
not possible (by design) with of-platdata.
Add a way for drivers to record the of-platdata index of their emulator,
so that we can still find the emulator.
This allows i2c emulation to work with of-platdata.
