wl12xx: Set different wake up conditions in case of suspend
Added ability to set different wake up conditions for suspend/resume. Set default values to wake up every 3 DTIMs while suspended and every 1 DTIM while resumed Signed-off-by: Eyal Shapira <eyal@wizery.com> Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
