Per binding doc fsl,aips-bus.yaml, compatible and reg is
required. And for reg, the AIPS configuration space should be
used, not all the AIPS bus space.

Any reason that we need to add the aips bus compatible & reg back? The aips config space
can only be write by secure world, linux has no permission to config the aips port. And it seems
no driver use "fsl,aips" anymore.
