parallel: Drop explicit fallback_chip_X boilerplate

Browse Source 
A NULL func pointer is necessary and sufficient for the
condition `NULL func pointer => fallback_chip_X' as to not
need this explicit specification.

Therefore drop the explicit need to specify these fallback
callback function pointer in the par_master struct.
This is a reasonable default for every driver in the tree.

Furthermore, move the 'fallback_chip_X()' func from the
generic programmer.c register logic into its relevant
home of parallel.c and make static local to clean up
link-time symbol space.

This simplifies the code and driver development.
