net: ethernet: ti: davinci_cpdma: make function cpdma_desc_pool_creat…

…e static

The function cpdma_desc_pool_create is local to the source and does not
need to be in global scope, so make it static.

Cleans up sparse warning:
warning: symbol 'cpdma_desc_pool_create' was not declared. Should it
be static?
