Arnd Bergmann 84bffa5f38 ARM: PL011: Fix DMA support 
commit 58ac1b3799799069d53f5bf95c093f2fe8dd3cc5 upstream.

Since there is no guarantee that the memory returned by
dma_alloc_coherent() is associated with a 'struct page', using the
architecture specific phys_to_page() is wrong, but using
virt_to_page() would be as well.

Stop using sg lists altogether and just use the *_single() functions
instead. This also simplifies the code a bit since the scatterlists in
this driver always have only one entry anyway.
