NPU firmware requires a host-allocated work buffer for hardware contexts. Allocate a 4 MB host buffer and attach it to device during device init. Refactor aie2_alloc_msg_buffer() and aie2_free_msg_buffer() into common helpers by moving them to aie.c and renaming them to amdxdna_alloc_msg_buffer() and amdxdna_free_msg_buffer(), allowing both AIE2 and AIE4 to reuse the implementation.
