dt-bindings: dma: qcom,bam: require one of control methods
The BAM DMA resources can be controlled remotely (e.g. by trusted
environment; needs qcom,powered-remotely or qcom,controlled-remotely
properties) or locally. In the latter case we need to provide its
clock.
Require one of methods of such control to properly validate DTS.
