Both drivers CPSW and EMAC can't work without CPDMA, hence simplify build
of those drivers by always linking davinci_cpdma and drop TI_DAVINCI_CPDMA

Note. the davinci_emac driver module was changed to "ti_davinci_emac" to
make build work.

Last time I tried including the same object file in two different
modules it backfired pretty badly. Would you mind sparing some
details as to why you need to do this?

How did you get to know they backfired? make allmodconfig will catch the issue??
