[PATCH v6 6/6] arm64: dts: imx8mp: make 'dsp' node depend on 'aips5'

[Laurentiu Mihalcea]

From: Laurentiu Mihalcea <laurentiu.mihalcea@xxxxxxx>

The DSP needs to access peripherals on AIPSTZ5 (to communicate with
the AP using AUDIOMIX MU, for instance). To do so, the security-related
registers of the bridge have to be configured before the DSP is started.
Enforce a dependency on AIPSTZ5 by adding the 'access-controllers'
property to the 'dsp' node.
