include: Add xmalloc, xzmalloc and dma routines

Add a Kconfig value to indicate coreboot builds.

Add prototypes and definitions for:
* dma_coherent
* dma_malloc
* xmalloc
* xzmalloc

Move prototype for memset into stdlib.h from string.h to eliminate build
breaks.

TEST=Build and test on Galileo Gen2
