[PATCH 4/5] arm64: dts: imx8mp: convert 'aips5' to 'aipstz5'

[Laurentiu Mihalcea]

From: Laurentiu Mihalcea <laurentiu.mihalcea at nxp.com>

AIPS5 is actually AIPSTZ5 as it offers some security-related
configurations. Since these configurations need to be applied before
accessing any of the peripherals on the bus, it's better to make AIPSTZ5
be their parent instead of keeping AIPS5 and adding a child node for
AIPSTZ5. Also, because of the security configurations, the address space
of the bus has to be changed to that of the configuration registers.

Finally, since AIPSTZ5 belongs to the AUDIOMIX power domain, add the
missing 'power-domains' property. The domain needs to be powered on before
attempting to configure the security-related registers.

The DT node name is not changed to avoid potential issues with DTs in
which this node is referenced.
