interrupt.rs:
- InterruptRemapTable now owns optional DmaBuffer for self-allocated tables
- new_allocated(entry_count) constructor allocates physically contiguous
DMA memory via DmaBuffer::allocate, returns Result
- new(base_addr, size) still works for externally-provided tables
- private addr() helper replaces direct 'base' field access
- len_encoding() returns AMD-Vi log2-encoded IRT length for DTE entries
- physical_address() returns table base physical address
- Remove unused 'warn' and 'error' imports from log crate
amd_vi.rs:
- Use InterruptRemapTable::new_allocated instead of ::new for IRT init
- Cast len_encoding() from u64 to u8 for DeviceTableEntry::set_int_table_len
Verified: iommu crate compiles clean (0 errors, 0 warnings).
