Stian Halseth d5b5e8149a sparc: Fix page alignment in dma mapping 
'phys' may include an offset within the page, while previously used
'base_paddr' was already page-aligned. This caused incorrect DMA mapping
in dma_4u_map_phys and dma_4v_map_phys.

Fix both functions by masking 'phys' with IO_PAGE_MASK, covering both
generic SPARC code and sun4v.

Fixes: 38c0d0ebf5 ("sparc: Use physical address DMA mapping")
