sh: sm501: add 2D engine support

In linux kernel v2.6.33, sm501 frame buffer driver modified to support
2D graphics engine on sm501 chip. One example is "fill rectangle" operation.
But current qemu's sm501 emulation doesn't support it. This results in
graphics console disturbance.

This patch introduces sm501 2D graphics engine emulation and solve this problem.

Add SM501 2D hardware engine support.
- Add 2D engine register set read/write handlers.
     - Support 'fill rectangle'. Other operations are left for future work.
     - Update SM501 support status comment.
