Subject: [PATCH v2 2/5] dt-bindings: dsp: fsl,dsp: document 'access-controllers' property

From: Laurentiu Mihalcea <laurentiu.mihalcea@....com>

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.
