MIPS: DMA: Add cma support
Adds cma support to the MIPS architecture.
cma uses memblock. However, mips uses bootmem.
bootmem is informed about any regions reserved by memblock
dma api is modified to use cma reserved memory regions when available
Tested using cma_test. cma_test is a simple driver that assigns blocks
of memory from cma reserved sections.
