adec566b05 dmaengine: bestcomm: fix system boot lockups 
memset() and memcpy() on an MMIO region like here results in a
lockup at startup on mpc5200 platform (since this first happens
during probing of the ATA and Ethernet drivers). Use memset_io()
and memcpy_toio() instead.

9a32299394 powerpc, dma: move bestcomm driver from arch/powerpc/sysdev to drivers/dma 
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.
