Yes, I feel that the changes required to introduce chip.c files are balooning, and Jenkins is currently showing many linker errors.  I need to land this refactoring (accepting new Ti50 identification), before I can land the Ti50 change to start presenting the new identification, and I want to do the latter before an upcoming FSI of Ti50 firmware.

I think I am going to split this CL into a pure Kconfig refactoring, and then another CL that introduces chip.c files, and rectifies the conditions under which that code is compiled and linked.  Stay tuned.

Done

Many of these small inline functions are being used both from the methods now in the new chip.c file, as well as methods remaining in tis.c.  I have created a new tis.h to contain shared macros and inline function definitions.
