dma-coherent: use KiB in DMA allocation logs
Update DMA reserved memory pool allocation log messages to display
sizes in KiB instead of MiB. Using MiB caused allocations less than
1 MiB to be logged as 0 MiB due to integer truncation. KiB provides
better precision for smaller memory regions specified in the Device Tree.
