[PATCH V3 11/15] arm64: dts: imx8: split adma ss into dma and audio ss

[Dong Aisheng <aisheng.dong@nxp.com>]

amda ss is consisted of dma and audio ss in qxp which are
also used in qm.
Let's split them into two ss for better code reuse.

Tested-by: Oliver Graute <oliver.graute@kococonnector.com>

ChangeLog:
v2->v3:
 * use new clock-indices IDs
 * remove ss prefix for adma
v1->v2:
 * change to the new two cell scu clk binding
