There is no reason in rx_descs property because davinici_cpdma
driver splits pool of descriptors equally between tx and rx channels.
So, this patch series makes driver to use available number of
descriptors for rx channels.

Based on
git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next.git
master

Since v2:
- add declaration of buf_num in correct order

Series applied, thanks.
