[ARM] pxafb: add support for FBIOPAN_DISPLAY by dma braching
dma branching is enabled by extending the current setup_frame_dma()
function to allow a 2nd set of frame/palette dma descriptors to be
used.
As a result, pxafb_dma_buff.dma_desc[], pxafb_dma_buff.pal_desc[]
and pxafb_info.fdadr[] are doubled.
This allows maximum re-use of the current dma setup code, although
the pxafb_info.fdadr[xx] for FBRx register values looks a bit odd.
