jak_capb signs of life (nw) (#4569)
* spg110 data segment (nw) * dummy (nw) * (nw) * notes on possible register use (nw) * jak_capb signs of life (nw) * better tile addressing (nw) * (nw) * (nw) * yeah palette format is another strange one, not quite right, code borrowed from another driver (nw) * some scroll (nw) * (nw) * seems to be step (nw) * be more scrolly (nw)

SunPlus SPG110-series SoC peripheral emulation
- It is possible this shares some video features with spg110 and
- can be made a derived device
+ 0032xx looks like it could be the same as 003dxx on spg2xx
+ but the video seems quite different?
