Currently DaVinci EDMA driver supports multiple EDMA channel controller
instances.  edma_alloc_channel() api returns a 32 bit value which has the
channel controller number in MSB and the EDMA channel number in LSB.  The
variables which store the value returned by edma_alloc_channel() have to
be 32 bit wide now.
