[PATCH] video: ocfb: Fix data type warning

From: Qiang Chen
Date: Fri Dec 05 2014 - 03:19:18 EST

When allocate framebuffer memory using dma_alloc_coherent(),
we'd better use dma_addr_t instead of phys_addr_t. Because the
address we got in fact is DMA or bus address for the platform.

This patch also fixes below build warning:
warning: passing argument 3 of âdma_alloc_attrsâ
from incompatible pointer type [enabled by default]
