rockchip: rk322x: Disable integrated macphy for saving power consuming
Unfortunately, the integrated macphy default is enabled, which will
increase power consuming, if we do not use this PHY. So let's disable
it at first, which will save power consuming. If we really use it, then
enable it in driver level.
