Anatolij Gustschin 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.

Fixes: 2f9ea1bde0 ("bestcomm: core bestcomm support for Freescale MPC5200")
