kfifo: don't include dma-mapping.h in kfifo.h
[ Upstream commit 44059790a5cb9258ae6137387e4c39b717fd2ced ]
Nothing in kfifo.h directly needs dma-mapping.h, only two macros
use DMA_MAPPING_ERROR when actually instantiated. Drop the
dma-mapping.h include to reduce include bloat.
Add an explicity <linux/io.h> include to drivers/mailbox/omap-mailbox.c
as that file uses __raw_readl and __raw_writel through a complicated
include chain involving <linux/dma-mapping.h>
