msm: camera: common: Fix integer overflow in shift
Various drivers are using right shift by 32 to check if dma address is 32 bit addressable. This will result in shift count overflow in 32 bit arch. CRs-Fixed: 2543730 Change-Id: I57e30bc9c0a8179c8d74f3bd3b6567bdfff60741 Signed-off-by: Trishansh Bhardwaj <tbhardwa@codeaurora.org>
