sconfig: Add 10bit addressing mode to i2c device type

Browse Source 
Use the second token for an i2c device entry in devicetree.cb to
indicate if it should use 10-bit addressing or 7-bit.  The default if
not provided is to use 7-bit addressing, but it can be changed to
10-bit addressing with the ".1" suffix.  For example:

chip drivers/i2c/generic
  device i2c 3a.1 on end
end
