Subject: [PATCH] dmaengine: pl330: Typecast with enum to fix the coverity warning

From: Shravya Kumbham <shravya.kumbham@...inx.com>

Typecast the flags and flg variables with (enum dma_ctrl_flags) in
pl330_prep_dma_cyclic, pl330_prep_dma_memcpy and pl330_prep_slave_sg
functions to fix the coverity warning.

Addresses-Coverity: Event mixed_enum_type.
