device/i2c_bus: allow i2c_bus and i2c_simple to coexist

Browse Source 
If one wants to implement both i2c_bus.h and i2c_simple.h APIs
the compilation unit needs to be guarded or coordinated carefully
with different compilation units. Instead, name the i2c_bus
functions with _dev such that it indicates that they operate on
struct device. One other change to allow i2c_bus.h to be built in
non-ramstage environments is to ensure DEVTREE_CONST is used for
the dev field in struct bus.
