accel/amdxdna: Add carveout memory support for non-IOMMU systems
Add support for allocating buffers from reserved carveout memory when
IOMMU is not available. This is useful during debugging or bring-up.
In this configuration, the device uses physical addresses and does
not support scatter-gather lists, requiring physically contiguous
buffers.
Implement carveout-backed allocation and integrate it into buffer
management to support operation in physical address mode.
