MIPS: Fix oops in dma_unmap_page on not coherent mips platforms

Browse source

dma_cache_wback_inv() expects virtual address, but physical was provided
due to translation via plat_dma_addr_to_phys().
If replaced with dma_addr_to_virt(), page fault oops from dma_unmap_page()
is gone on au1550 platform.
