It may be useful at times to boot ADSP via backdoor, even
while system boots via front door. MB2 sets the ACAST in
front door, so ACAST setting from nvadsp driver is skipped
if that region is already enabled.
Above scheme will work for ADSP backdoor boot via SMMU
mapped memory, but not for physical memory, as the underlying
carveout memory is different between frontdoor and backdoor.

ACAST settings are expected to be done by the driver in backdoor
boot. Provision is added to read the ACAST address ranges and
the SMMU stream ID from DT.
ACAST settings are done either for physical memory, or for SMMU
mapped memory, as per the backdoor boot configuration.
Also, call to ACAST init function is moved from runtime resume
to device probe.
