hw: Remove unnecessary cast when calling dma_memory_read()
Since its introduction in commit d86a77f8abb, 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. Signed-off-by: Philippe Mathieu-Daudé <philmd@redhat.com> --- v4: Drop parenthesis when removing cast (Eric Blake)
