arm64: dts: qcom: sm8350: fix BAM DMA crash and reboot

SM8350 HDK and MTP boards were silently dying and rebooting during BAM
DMA probe, probably during reading BAM_REVISION register:

  [    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 not yet operational, thus mark it as failed and
disable also QCE because it won't work without BAM DMA.
