DaVinci EMAC: Fix davinci_eth_gigabit_enable
Enabling the gigabit was overwriting the previous configuration by setting up only GIGAFORCE and GIG bits of MAC control register. Modified to retain previous configuration while gigabit enabling. Signed-off-by: Prakash PM <prakash.pm@ti.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
