optimize conf.c code part 2

The initial config can be greatly simplified and be made more compact.

Before this change:

   text    data     bss     dec     hex filename
   1530       0       0    1530     5fa conf.o

After this change:

   text    data     bss     dec     hex filename
   1036       0       0    1036     40c conf.o
