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.
Fixes: f1040a7fe8f0 ("arm64: dts: qcom: sm8350: Add Crypto Engine support")
