cpsw: add driver for cpsw ethernet device
CPSW is an on-chip ethernet switch that is found on various SoCs from Texas
Instruments. This patch adds a simple driver (based on the Linux driver) for
this hardware module.
This patch also adds support to clean and flush dcache during packet send
and receive.
Changes by Sandhya: Added support to clean and flush dcache during packet
send/receive and added timeouts.
