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.
