drm/i915: Refactor setting dma info to a common helper
DMA_MASK bit values are different for different generations.
This will become more difficult to manage over time with the open
coded usage of different versions of the device.
Fix by:
disallow setting of dma mask in AGP path (< GEN(5) for i915,
add dma_mask_size to the device info configuration,
updating open code call sequence to the latest interface,
refactoring into a common function for setting the dma segment
and mask info
