This patch uses memset_io instead of memset when using memset on __iomem
qualified pointers. This fixes the following sparse warnings:-

drivers/staging/sm750fb/sm750.c:489:17: warning: incorrect type in argument 1 (different address spaces)
drivers/staging/sm750fb/sm750.c:490:17: warning: incorrect type in argument 1 (different address spaces)
