ipq806x: disable DMA on the SPI flash

Previous patch 6f2905eeb6ce5ddec8d12d677e1f377a940b537b enabled ADM in
the kernel, which causes a kernel panic when accessing the SPI flash.

As a workaround, We'll disable DMA for the flash for now. It was not
enabled previously anyway so we'll just leave it as is.
