Thomas Veerman ba49a155b5 fb: introduce framebuffer support to Minix
This patch introduces a framebuffer to Minix. It's written for the ARM
port of Minix, but has an architectural split that separates the
hardware dependent part from the non-hardware dependent part. Futhermore,
this driver was developed using a screen that has a native resolution of
1024x600 pixels and having lack of support for obtaining EDID from the
screen. Consequently, it uses a hardcoded resolution of 1024x600.

The driver uses an interface based on the Linux ioctl API, but supports
only a very limited subset.
