wl18xx: add some boot operations and hw-specific configurations
Implement the boot operation. Add a wl18xx-specific configuration structure (namely to configure the mac and phy parameters). The default hw configuration matches the DVP board. Signed-off-by: Luciano Coelho <coelho@ti.com> Signed-off-by: Arik Nemtsov <arik@wizery.com>
