davinci: cpu-specific build uses conditional make syntax
Update cpu/arm926ejs/davinci/Makefile to use COBJ-y type syntax.
Add the first conditional: for EMAC driver support. Not all
chips have an EMAC; and boards might not use it, anyway.
This doesn't touch PHY configuration; that should eventually
become conditional too.
