Viswanath L 5713bc51b0 nvadsp: Use dynamically allocated shared mem ...

Upstream kernel does not export IOMMU APIs, so use dynamic
memory allocation for shared memory in non-secure boot mode.

Move stale code that uses IOMMU APIs under macro
CONFIG_IOMMU_API_EXPORTED. As remapping allocated IOVA to a fixed
address is no longer possible, IOVA cannot be used for OS memory;
reserved physical memory may be used in its place.

Dynamic memory allocation for shared memory will be selected if
ACSR_ADDR in "nvidia,adsp_mem" DT property is set to 0.
