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.
