The previous code could use the first USB-DMAC with IPMMU if iommus
property was set into this device node. However, in this case, it
could not control the second USB-DMAC with IPMMU because a parameter
of IPMMU (micro-TLB id) is different with each USB-DMAC.
So, this patch uses the usb_gadget_{un}map_request_by_dev() APIs for
IPMMU. (Then, iommus property should be set into USB-DMAC node(s).)
