i3c: mipi-i3c-hci: Consolidate DMA ring allocation

dma_alloc_coherent() allocates memory in whole pages, which can waste
space when command and response queues are allocated separately.

Allocate the DMA command and response queues from a single coherent
allocation instead, while preserving the required 4-byte alignment.

This reduces memory overhead without changing behavior.
