This patch adds missing dma DTS definitions for omap aes and sham drivers.
Without it kernel drivers do not work for device tree based booting
while it works for legacy booting on general purpose SoCs.

Note that further changes are still needed for high secure SoCs. But since
that never worked in legacy boot mode either, those will be sent separately.
