net: davinci_emac: convert to using the driver model
Now that we removed all legacy boards selecting TI_EMAC we can completely convert the driver code to using the driver model. This patch also updates all remaining users of davinci_emac. Signed-off-by: Bartosz Golaszewski <bgolaszewski@baylibre.com> Tested-by: Adam Ford <aford173@gmail.com> #am3517-evm & da850-evm Reviewed-by: Ramon Fried <rfried.dev@gmail.com>
