arm64: dts: qcom: sdm845: move DSI/QUP/QSPI opp tables out of SoC node

The SoC node is a simple-bus and its schema expect to have nodes only
with unit addresses:

  sdm850-lenovo-yoga-c630.dtb: soc@0: opp-table-qup: {'compatible': ['operating-points-v2'], 'phandle': [[60]], 'opp-50000000':
  ... 'required-opps': [[55]]}} should not be valid under {'type': 'object'}

Move to top-level OPP tables:
 - DSI and QUP which are shared between multiple nodes,
 - QSPI which cannot be placed in its node due to address/size cells.
