Lucas De Marchi e40785b002 AP_HAL_Linux: Add fake device to I2CDriver
This allows us to re-use I2CDevice from I2CDriver while the drivers are
converted.  We create a fake device with addr = 0 for each I2CDriver but
we only use the register/unregister logic. The transfer logic still uses
the methods from I2CDriver in order to use the right address.

Now we can interoperate I2CDevice drivers with the ones base in
I2CDriver since they are going to use the same semaphore and bus.

The I2CDriver constructors were changed to re-use the logic in I2CDevice
(it uses a number rather than an string) and the semaphore doesn't live
outside anymore, its embedded in the fake I2CDevice, as well as the
bus's file descritor.
