The caif_shmcore requires io.h in order to use ioremap, so include that explicitly to compile in all configurations. Also add a note about the use of ioremap(), which is not a proper way to map a DMA buffer into kernel space. It's not completely clear what the intention is for using ioremap, but it is clear that the result of ioremap must not simply be accessed using kernel pointers but should use readl/writel or memcopy_{to,from}io. Assigning the result of ioremap to a regular pointer that can also be set to something else is not ok.
