Philippe Mathieu-Daudé 18610bfd3e hw: Remove unnecessary cast when calling dma_memory_read()
Since its introduction in commit d86a77f8ab, dma_memory_read()
always accepted void pointer argument. Remove the unnecessary
casts.

This commit was produced with the included Coccinelle script
scripts/coccinelle/exec_rw_const.
