[PATCH] arm64: dts: qcom: sm8350: fix BAM DMA crash and reboot

[Krzysztof Kozlowski]

SM8350 HDK and MTP boards were silently dying and rebooting during BAM
DMA probe:

  [    1.574304] vreg_bob: Setting 3008000-3960000uV
  [    1.576918] bam-dFormat: Log Type - Time(microsec) - Message -
  Optional Info
  Log Type: B - Since Boot(Power On Reset),  D - Delta,  S - Statistic
  S - QC_IMAGE_VERSION_STRING=BOOT.MXF.1.0-00637.1-LAHAINA-1
  S - IMAGE_VARIANT_STRING=SocLahainaLAA
  S - OEM_IMAGE_VERSION_STRING=crm-ubuntu77
  S - Boot Interface: UFS

It seems that BAM DMA is locally controller (not by firmware) and
requires proper initialization by the driver prior to use, at least on
HDK8350 and MTP8350, but probably on all boards.
