[PATCH] drm/etnaviv: dump DMA registers first

[Derek Foreman]

On at least some hardware, reading one of these other registers has the
side effect of changing the DMA address register, making dumps much less
useful.

Move some DMA registers to the top of the list to increase the chance of
getting a useful devcoredump.
