ion: ion_sync_for_device use swiotlb_dma_ops not dummy_dma_ops [1/1]

PD#OTT-5276

Problem:
CTS EncodeDecodeTest failed. Ion sync ioctrl was
forwarded to a dummy implementation. So cached dma buffer
syncing between device and driver was inconsistent occasionally.

Solution:
Changed the dummy_dma_ops to swiotbl_dma_ops when ion_sync_for_device

Verify:
franklin, hertz
