Sugar Zhang c17fb06672 dmaengine: pl330: _prep_dma_memcpy: Fix wrong burst size 
[ Upstream commit e773ca7da8beeca7f17fe4c9d1284a2b66839cc1 ]

Actually, burst size is equal to '1 << desc->rqcfg.brst_size'.
we should use burst size, not desc->rqcfg.brst_size.

dma memcpy performance on Rockchip RV1126
