Generic device properties framework updates for v4.11-rc1

Allow built-in (static) device properties to be declared
 as constant, make it possible to save memory by discarding
 alternative (but unused) built-in (static) property sets and
 add support for automatic handling of built-in properties
 to the I2C code.
