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.
