net: lwm2m: fix float32/64 handling During the initial work on LwM2M, the float32/64 code was basically stubbed out. Float32 sent only whole values and float64 was completely broken. Let's clean up the OMA TLV formatting code by moving the float processing code into a separate file: lwm2m_util.c. Then using public definitions for binary32 and binary64, let's fix the processing code to correctly fill the float32_value_t and float64_value_t types.
