[PATCH] mbxfb: Add framebuffer driver for the Intel 2700G

Add frame buffer driver for the 2700G LCD controller present on CompuLab
CM-X270 computer module.

[adaplas]
- Add more informative help text to Kconfig
- Make DEBUG a Kconfig option as FB_MBX_DEBUG
- Remove #include mbxdebug.c, this is frowned upon
- Remove redundant casts
- Arrange #include's alphabetically
- Trivial whitespace
