dmaengine: omap-dma: Enable burst and data pack for SG
Enable the burst and data pack modes for the scatter-gather
in order to improve the throughput of the data transfers.
The improvement has been verified with MMC HS200 mode in
the DRA72 EVM using the iozone tool to compare the read
throughput (in kB/s) with and without burst/pack for
different reclens (in kB).
