The bestcomm dma hardware, and some of its users like the FEC ethernet component, is used in different FreeScale parts, including non-powerpc parts like the ColdFire MCF547x & MCF548x families. Don't keep the driver hidden in arch/powerpc where it is inaccessible for other arches. .c files are moved to drivers/dma/bestcomm, while .h files are moved to include/linux/fsl/bestcomm. Makefiles, Kconfigs and #include directives are updated for the new file locations. Tested by recompiling for MPC5200 with all bestcomm users enabled.
