Commit 4972a80e16a2 (ARM: SAMSUNG: Add device tree support for pl330 dma engine
wrappers) introduced a new member 'dt_dmach_prop' in the struct samsung_dma_info
which is used to specify the dma channel number property as obtained from the
device tree. It also introduced a new dma request id 'DMACH_DT_PROP' to indicate
that a device tree node property represting the dma channel is available in
'struct samsung_dma_info'.
Add dma request id 'DMACH_DT_PROP' in s3c64xx dma channel id list in order to
maintain compatibility to the changes in the Samsung dma wrappper operations.
