Some DSP instances may have their access to certain peripherals
conditioned by a bus access controller such as the one from the
AIPSTZ bridge.
Add the optional 'access-controllers' property, which may be used
in such cases.

Subject: [PATCH v5 3/6] bus: add driver for IMX AIPSTZ bridge

From: Laurentiu Mihalcea <laurentiu.mihalcea@nxp.com>
The secure AHB to IP Slave (AIPSTZ) bus bridge provides access control
configurations meant to restrict access to certain peripherals.
Some of the configurations include:
1) Marking masters as trusted for R/W. Based on this
(and the configuration of the accessed peripheral), the bridge
may choose to abort the R/W transactions issued by certain
masters.
2) Allowing/disallowing write accesses to peripherals.
Add driver for this IP. Since there's currently no framework for
access controllers (and since there's currently no need for having
flexibility w.r.t the configurations) all this driver does is it
applies a relaxed, "default" configuration, in which all masters
are trusted for R/W.
Note that some instances of this IP (e.g: AIPSTZ5 on i.MX8MP) may be tied
to a power domain and may lose their configuration when the domain is
powered off. This is why the configuration has to be restored when the
domain is powered on.

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.

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.
