Nicolas Ferre 9b3aa589ea dmaengine: at_hdmac: modify way to use interrupts
Now we use Buffer Transfer Completed interrupts. If we
want a chained buffer completed information, we setup the
ATC_IEN bit in CTRLB register in the lli.
This is done by set_desc_eol() function and used by
memcpy/slave_sg functions.
